ABSTRACT
ObjectiveTo explore the mechanism of Bushen Huoxue enema in treating the rat model of kidney deficiency and blood stasis-thin endometrium （KDBS-TE） by transcriptome sequencing. MethodThe rat model of KDBS-TE was established by administration of tripterygium polyglycosides tablets combined with subcutaneous injection of adrenaline. The pathological changes of rat endometrium in each group were then observed. Three uterine tissue specimens from each of the blank group， model group， and Bushen Huoxue enema group were randomly selected for transcriptome sequencing. The differentially expressed circRNAs， lncRNAs， and miRNAs were screened， and the disease-related specific competitive endogenous RNA （ceRNA） regulatory network was constructed. Furthermore， the gene ontology （GO） functional annotation and the Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment were performed for the mRNAs in the network. ResultCompared with the blank group， the model group showed endometrial dysplasia， decreased endometrial thickness and endometrial/total uterine wall thickness ratio （P<0.01）， and differential expression of 18 circRNAs， 410 lncRNAs， and 7 miRNAs. Compared with the model group， the enema and estradiol valerate groups showed improved endometrial morphology and increased endometrial thickness and ratio of endometrial to total uterine wall thickness （P<0.05）. In addition， 21 circRNAs， 518 lncRNAs， and 17 miRNAs were differentially expressed in the enema group. The disease-related specific circRNA-miRNA-mRNA regulatory network composed of 629 nodes and 664 edges contained 2 circRNAs， 34 miRNAs， and 593 mRNAs. The lncRNA-miRNA-mRNA regulatory network composed of 180 nodes and 212 edges contained 5 lncRNAs， 10 miRNAs， and 164 mRNAs. The mNRAs were mainly enriched in Hippo signaling pathway， autophagy-animal， axon guidance， etc. ConclusionBushen Huoxue enema can treat KDBS-TE in rats by regulating specific circRNAs， lncRNAs， and miRNAs in the uterus and the ceRNA network.
ABSTRACT
Introduction: Menorrhagia is one of the commonest clinical conditions for which patients seek advice in the gynecological outpatient department. Aim and objectives of study: To determine the prevalence of various histopathological changes, patterns and lesions of endometrium associated with menorrhagia in the women of different age groups; to describe the morphological features of various lesions of endometrium; to assess demographic pattern of various types of endometrium lesions in this part of our country and to do clinicopathological correlation and give diagnosis based on it. Materials and methods: This was a prospective, non-interventional and observational hospital based crosssectional one year study carried out between January 2020 to June 2021 in Histopathology Department of Dhiraj Hospital on 52 cases of D & C and hysterectomy specimens. All the specimens were fixed in 10% formalin were received in the department of Pathology and processed and embedded in paraffin wax. Multiple serial sections of 4-5 microns thickness were obtained from the paraffin block and then stained with H & E. Detailed study of the sections was done by light microscopy. Results: 52 cases of menorrhagia were studied clinically and histopathologically. In present study, large proportion of patients with menorrhagia showed proliferative endometrial pattern (38.46%) followed by secretory phase (34.62%). Hyperplastic pattern was seen in 13.46% of patients. Non hyperplastic endometrial pattern was more common than hyperplastic pattern. Simple hyperplasia was more commonly seen than complex and atypical hyperplasia. Overall incidence of atypical hyperplasia was low (28.57%) and atrophic endometrium seen in 5.7% of cases. Endometrial polyp was seen in 3.84% cases and endometrial carcinoma was seen in 3.84% cases. Conclusion: Histopathological study of endometrium is very useful to reveal different endometrial patterns in menorrhagia and to distinguish between anovulatory and ovulatory causes. It is also useful for the diagnosis of endometrial hyperplasia and endometrial carcinoma.
ABSTRACT
Background: Abnormal uterine bleeding (AUB) or menstrual bleeding of abnormal amount, duration, or schedule is a common gynecological condition occurring in up to 50% of women of all age groups. Chronic, heavy, prolonged, or irregular uterine bleeding can lead to anemia, and raise a concern about severe underlying malignancy. Therefore, histopathological examination of the endometrium is critical in evaluating the cause of AUB. Aims and Objectives: The aims of this study were to study the various histomorphological patterns in endometrial biopsies in cases of AUB. Materials and Methods: This is a retrospective study done on 212 endometrial tissues in women presenting with AUB. The study is aimed at analyzing the histopathological changes occurring in the endometrium by identifying the cause of bleeding and recording the incidence of various histopathological findings in different age groups. Results: Proliferative endometrium, the most common histopathological finding, accounted for 51.9% of cases, followed by secretory endometrium (24.5%). Eight cases of disordered proliferative endometrium were found in the present study. Eight cases, accounting for 3.8% of endometrial hyperplasia, were associated with AUB, out of which two cases were found to be complex hyperplasia with atypia. Endometrial carcinoma was seen in two cases associated with AUB. Pregnancy-related changes were found in 7 (3.3%) cases, retained product of conception was the leading cause of bleeding (3 cases). Conclusion: Histopathological evaluation of endometrium in women presenting with AUB is of paramount importance not only to diagnose various benign conditions but also to detect some highly malignant lesions and precancerous conditions so that early interventions can be started.
ABSTRACT
OBJECTIVE@#To compare the clinical efficacy between staged acupuncture based on "thoroughfare vessel is the sea of blood" theory combined with routine hormone replacement cycle treatment and routine hormone replacement cycle treatment for patients with recurrent implantation failure (RIF) of thin endometrium.@*METHODS@#A total of 72 RIF patients with thin endometrium were randomly divided into an observation group and a control group, 36 cases in each group. The patients in the control group were treated with routine hormone replacement cycle treatment. Based on the treatment of the control group, the patients in the observation group were treated with staged acupuncture based on "thoroughfare vessel is the sea of blood" theory. The main acupoints were Neiguan (PC 6) and Gongsun (SP 4), and the supplementary acupoints were selected according to the menstrual cycle and syndrome differentiation; the acupuncture was given once every other day, 3 times a week, for 3 consecutive menstrual cycles. The thickness and shape of endometrium, and Hamilton anxiety scale (HAMA) score were observed at implantation window before and after treatment; the clinical pregnancy rate, live birth rate and cycle cancellation rate were compared between the two groups; the correlation between endometrial thickness and HAMA score was analyzed.@*RESULTS@#Compared before treatment, the endometrial thickness in the two groups and the proportion of type A+B endometrium in the observation group were increased (P<0.05), and the HAMA scores in the two groups were decreased (P<0.05) after treatment. The above indexes in the observation group were superior to those in the control group (P<0.05). The clinical pregnancy rate and live birth rate in the observation group were higher than those in the control group (P<0.05), and the cycle cancellation rate was lower than that in the control group (P<0.05). There was a negative correlation between endometrial thickness and HAMA score (P<0.05).@*CONCLUSION@#Based on the routine hormone replacement cycle treatment, the addition use of staged acupuncture based on "thoroughfare vessel is the sea of blood" theory could improve the thickness and shape of endometrium, relieve anxiety, increase the clinical pregnancy rate and live birth rate, and reduce the cycle cancellation rate in RIF patients with thin endometrium. The curative effect is superior to the routine hormone replacement cycle treatment alone.

ABSTRACT Xanthogranulomatous inflammation is a rare benign inflammatory lesion characterized by sheets of lipid-laden foamy histiocytes. It has been reported in various organs, mainly the kidney and gall bladder. Xanthogranulomatous endometritis (XGE) is sporadic, with only a few cases reported in the English medical literature. Herein, we report a case of xanthogranulomatous endometritis with the formation of stones in a 50-year-old female patient with a prolapsed uterus. Grossly the endometrium was irregular, and the uterine cavity was filled with a yellow friable material, a polypoid growth, and yellowish stones. The microscopy showed sheets of histiocytes with few preserved endometrial glands. In this case, the xanthogranulomatous inflammation may mimic a clear cell carcinoma involving the endometrium and myometrium. One of the important differential diagnoses is malakoplakia. Immunohistochemistry and special stains are helpful in diagnosis.
ABSTRACT
SUMMARY OBJECTIVE: Our goal was to contrast the prognoses of patients with endometrial cancer who had adenomyosis against those that did not. METHODS: All patients who had received surgical staging for hysterectomy-based endometrial cancer had their medical data retrospectively examined. The analysis covered 397 patients, who were split into two groups depending on the presence of adenomyosis. Comparisons were made between patients covering type of surgery, histopathology, endometrial cancer stage, lymphovascular space invasion, presence of biochemical or histochemical markers, adjuvant therapy, presence of adenomyosis in the myometrial wall, and outcomes in terms of overall survival and disease-free survival. RESULTS: There is no statistically significant difference in the 5-year disease-free survival or overall survival rates between endometrial cancer patients with and without adenomyosis. This is based on comparisons of tumor stage, tumor diameter, histological type and grade of tumor, myometrial invasion, lymphovascular space invasion, and biochemical markers that affect the course of the disease. The median follow-up times were 61 months for the adenomyosis-positive group and 56 months for the group without adenomyosis. CONCLUSION: Coexisting adenomyosis in endometrial cancer has no bearing on survival rates and is not a prognostic factor.
ABSTRACT
Objective:To investigate the effect of follicular size on the clinical outcomes of frozen-thawed embryo transfer induced by human chorionic gonadotropin (hCG) of natural cycles on ovulation.Methods:Clinical data of 427 cycles of frozen-thawed single blastocyst transfer in Nanjing Drum Tower Hospital from January 2016 to December 2019 were retrospectively analyzed. The patients were divided into 15-16 mm group (15≤diameter≤16 mm, n=66), 16-17 mm group (16<diameter≤17 mm, n=101), 17-18 mm group (17<diameter≤18 mm, n=125), 18-20 mm group (18<diameter≤20 mm, n=109),>20 mm group (diameter>20 mm, n=26), according to the maximum follicle diameter on the induction day of hCG ovulation induction. The estradiol and luteinizing hormone (LH) levels, and clinical pregnancy rate, abortion rate and live birth rate were compared in five groups. Results:There were statistically significant differences in estradiol and LH levels among the five groups on the day of hCG induction (all P<0.05). Estradiol levels in 15-16 mm group to >20 mm group gradually increased on the day of hCG induction, and estradiol level in 15-16 mm group was significantly lower than those in 17-18 mm group, 18-20 mm group and >20 mm group (median: 1 002.3 vs 1 103.3 vs 1 171.2 vs 1 539.0 pmol/L), with statistical significances ( P=0.034, P<0.001, P=0.002). On the day of hCG induction, LH levels in 15-16 mm group to >20 mm group showed a decreasing trend, and LH level in 15-16 mm group was significantly higher than those in 17-18 mm group and >20 mm group (median: 37.73 vs 28.24 vs 24.11 U/L), with statistically significant differences ( P=0.007, P=0.006). There were no significant differences in clinical pregnancy rate, abortion rate and live birth rate in 15-16 mm group to >20 mm group (all P>0.05). Conclusion:In the natural cycle protocol of hCG induced ovulation, the small follicle group could achieve similar clinical outcomes compared with normal sized follicles in the single blastocyst transfer of frozen-thawed embryos.
ABSTRACT
Background: Abnormal uterine bleeding (AUB) is one of the most common problems encountered in gynecological practice. Various benign and malignant disorders of the endometrial tissue show vascular changes such as congestion, dilatation, and vessel wall irregularities. Aim: To evaluate the vascular morphometry of the endometrial tissue in AUB. Materials and Methods: A descriptive cross-sectional study of the endometrial tissue in patients presented with AUB was undertaken for vascular morphometric analysis. Histopathological processing of the endometrial tissue samples was done as per the standard format, and the slides were evaluated for vascular morphometry. Results: Out of 150 cases of endometrial tissue in patients presented with AUB, 80 cases were reported as proliferative phase, 41 as secretory phase, 15 as disordered proliferative endometrium, 6 as atrophic phase endometrium, and 4 each of endometrial hyperplasia without atypia and endometrial carcinoma. An average number of endometrial blood vessels and large-sized blood vessels were more in endometrial carcinoma and endometrial hyperplasia without atypia as compared to proliferative phase, secretory phase, atrophic endometrium, and disordered proliferative endometrium. Vessel shape irregularities and vascular congestion were observed in all the cases of atrophic endometrium, endometrial carcinoma, and endometrial hyperplasia without atypia. Endometrial carcinoma showed severe dilatation of the endometrial blood vessels. Conclusion: Vascular morphometry changes were noted in endometrial hyperplasia, endometrial carcinoma, disordered proliferative endometrium, and atrophic phase endometrium. These findings suggest that studies or trials related to anti-angiogenic therapy may help to plan anti-angiogenic therapy in patients with AUB.
ABSTRACT
Abstract Objective To assess the quality of recent meta-analyses reviewing the diagnostic utility of sentinel node biopsy in endometrial cancer. Methods With the MeSH terms endometrial neoplasms and sentinel lymph node biopsy, PubMed and Embase databases were searched on October 21, 2020, and again on November 10, 2021, with meta-analysis and publication date filters set to since 2015. The articles included were classified with the A Measurement Tool to Assess Systematic Reviews (AMSTAR 2) assessment tool. Results The database searches found 17, 7 of which, after the screening, were selected for full review by the author, finally extracting six meta-analyzes for quality analysis. The rating with the AMSTAR 2 assessment tool found that overall confidence in their results was critically low. Conclusion This study found that the quality of recent meta-analyses on the utility of the staging of endometrial cancer with sentinel node biopsy, evaluated by the AMSTAR 2 assessment tool, is classified as critically low, and, therefore, these meta-analyses are not reliable in the summary of their studies.

Background & objectives: Endometrial serous carcinoma (ESC) is a high-grade epithelial neoplasm with increased risk for metastasis and recurrence. This study was aimed to assess various histomorphological features of ESC and their clinicopathological association with disease-free survival (DFS) and overall survival (OS). Methods: A total of 205 slides (belonging to 120 patients) diagnosed as ESC from January 2009 to December 2015 were reviewed. Receiver operating characteristics (ROC) curves were established for the diagnostic performance of depth of invasion (DOI), tumour-free distance (TFD) to serosa and percentage myometrial invasion (MI%). OS and DFS were generated by Kaplan-Meier curves and prognostic significance by Cox regression analysis. Results: The mean age at diagnosis was 61.8 yr and the mean tumour size was 4.01 cm. Majority of the females were multiparous (84%; n=94) and postmenopausal (89.2%; n=107). On histopathology, <50 per cent of MI was identified in 37 of the 104 (35%), while 62/104 (59.61%) patients had ?50 per cent MI. Seven (6.7%) patients had full-thickness invasion with serosal involvement, while five (4.8%) patients had no microscopic MI (minimal uterine serous carcinoma). Information about MI was not available in 16 patients. TFD ?7.0 mm, DOI ?6.0 mm and MI% ?40 were significant variables in univariate analyses for OS; however, on multivariate analysis; none of these turned out to be an independent predictor in terms of OS. For DFS, DOI (?6.0 mm) and MI% (?40%) showed a significant association, in univariate as well as multivariate analysis; however, TFD (?7.0 mm) did not show any significant association with DFS. Follow up data were available in 111 of the 120 (92.5%) patients with a five-year OS and DFS of 22.2 and 17.2 per cent, respectively. Interpretation & conclusions: Conventionally calculated DOI (less than or more than half thickness) did not show significance in the present study. Thus, calculating the actual myometrial DOI, MI% and TFD to serosa have the potential for contributing meaningfully to prognostication of ESC
ABSTRACT
El tumor carcinoide de células caliciformes es una neoplasia mixta casi exclusiva del apéndice, con diferenciación neuroendocrina y mucinosa. La afección metastásica endometrial por carcinomas extragenitales, especialmente el tipo de células de anillo de sello, es rara. Se presenta un caso de tumor carcinoide de células caliciformes apendicular con metástasis endometrial. Se trató de paciente femenina de 70 años quien presentó sangrado genital. El examen ginecológico mostró sangrado genital en moderada cantidad de color rojo-marrón y cuello uterino endurecido. En la biopsia endometrial se halló nidos de células de anillo de sello. La impresión diagnóstica provisional fue carcinoma mal diferenciado de probable origen intestinal. Durante la intervención, el útero tenía consistencia pétrea, el apéndice cecal era fibrótico y engrosado y el epiplón engrosado con nódulos tumorales. Las secciones anatómicas del cuello y cuerpo uterino mostraron focos tumorales. En el apéndice cecal se encontró acúmulos de pequeño tamaño compuestos por células caliciformes. La inmunotinción fue positiva a sinaptofisina, CDX-2, EMA, CK20, CD56 focal. Estos hallazgos confirmaron el diagnóstico de tumor carcinoide de células caliciformes, un tumor caracterizado por infiltración de la pared apendicular por pequeños nidos o cordones de células caliciformes con mucina intracitoplasmática y expresión focal de marcadores neuroendocrinos. Estas neoplasias tienen un comportamiento más agresivo que los tumores neuroendocrinos. La metástasis endometrial es rara y puede ser confundida con un carcinoma primario de células de anillo de sello. Se debe considerar como diagnóstico diferencial después de excluir otros tumores primarios.
Goblet cell carcinoid tumor is an almost exclusive mixed neoplasm of the appendix with neuroendocrine and mucinous differentiation. Endometrial metastatic involvement by extragenital carcinomas, especially the signet ring cell type, is rare. A case of appendiceal goblet cell carcinoid tumor with endometrial metastasis is presented. This was a 70-year-old female patient who presented with genital bleeding. The gynecological examination showed moderate red-brown genital bleeding and hardened cervix. Endometrial biopsy reported nests of signet ring cells. The provisional diagnostic impression was poorly differentiated carcinoma of probable intestinal origin. During surgery, the uterus had a stony consistency, the cecal appendix was fibrotic and thickened, and the omentum was thickened with tumor nodules. Anatomical sections of the cervix and uterine body showed tumor foci. In the cecal appendix, small clusters composed of goblet cells were found. Immunostaining was positive for synaptophysin, CDX-2, EMA, CK20, focal CD56. These findings confirmed the diagnosis of goblet cell carcinoid tumor, a tumor characterized by infiltration of the appendiceal wall by small nests or cords of goblet cells with intracytoplasmic mucin and focal expression of neuroendocrine markers. These neoplasms have a more aggressive behavior than neuroendocrine tumors. Endometrial metastasis is rare and can be mistaken for a primary signet ring cell carcinoma. It should be considered as a differential diagnosis after other primary tumors have been excluded.
ABSTRACT
ABSTRACT Introduction: The success of frozen embryo transfer cycles depends on a delicate interaction between embryo quality and endometrium. Low pregnancy rates are associated with a thin endometrium. Objective: To evaluate the effect of autologous platelet-rich plasma treatment on patients with thin endometrium. Methods: In 34 patients with thin endometrium (< 7 mm), canceled in the previous frozen embryo transfer cycles, autologous platelet-rich plasma was prepared, from autologous peripheral vein blood; intrauterine infusion was given during hormone replacement therapy in frozen embryo transfer cycles. Frozen embryo transfer was performed when the endometrium thickness reached ≥ 7mm. Results: Six patients canceled the embryo transfer cycle due to endometrium thickness did not reach 7 mm; 28 patients got endometrial thickness ≥ 7 mm and performed frozen embryo transfer. The endometrial thickness was 7.5 ± 0.8 mm, which was significantly thicker than in the previous cycles (5.6 ± 0.79 mm) with p< 0.002, the implantation rate was 23.07 %, and the clinical pregnancy rate was 12/28 (42.8 %). Conclusion: Autologous platelet-rich plasma improves the endometrial thickness and the pregnancy rate outcomes in women with thin endometrium.
RESUMEN Introducción: El éxito de los ciclos de transferencia de embriones congelados depende de una delicada interacción entre la calidad del embrión y el endometrio. Las bajas tasas de embarazo están asociadas con un endometrio delgado. Objetivo: Evaluar el efecto del tratamiento con plasma rico en plaquetas autólogo en pacientes con endometrial delgado. Métodos: En 34 pacientes con endometrio delgado (< 7 mm) canceladas en los ciclos previos de transferencia de embriones congelados, se preparó plasma autólogo rico en plaquetas, a partir de sangre autóloga de venas periféricas; la infusión intrauterina se administró durante la terapia de reemplazo hormonal en los ciclos de transferencia de embriones congelados. La transferencia de embriones congelados se realizó cuando el grosor del endometrio alcanzó ≥ 7 mm. Resultados: En 6s pacientes se canceló el ciclo de transferencia embrionaria debido a que el grosor del endometrio no alcanzó los 7 mm; 28 pacientes obtuvieron un grosor endometrial ≥ 7 mm y realizaron transferencia de embriones congelados. El grosor del endometrio fue de 7,5 ± 0,8 mm, significativamente mayor que en los ciclos anteriores (5,6 ± 0,79 mm) con p< 0,002; la tasa de implantación fue de 23,07 % y la tasa de embarazo clínico fue de 12/28 (42,8 %). Conclusión: El plasma autólogo rico en plaquetas mejora el grosor endometrial y los resultados de la tasa de embarazo en mujeres con endometrio delgado.
ABSTRACT
Objective:To investigate the high risk factors for endometrial polyps (EP).Methods:The clinical data of 669 cases who underwent hysteroscopic examination due to abnormal vaginal bleeding and ultrasonic indications in Binzhou Medical University Hospital from October 2019 to September 2020 were retrospectively analyzed. According to postoperative pathological results, these patients were divided into an EP group ( n = 304) and a non-EP group ( n = 365). The clinical data of these patients were subjected to univariate and multivariate analysis using SPSS 22.0 software. Results:Univariate analysis showed that age (median age: 45 years in the EP group and 47 years in the non-EP group), number of pregnancies (median number of pregnancies: 2 in the EP group and 3 in the non-EP group), number of births (median number of births: 1 in the EP group and 2 in the non-EP group), menopause [49 cases (16.12%) in the EP group and 83 cases (22.74%) in the non-EP group], chronic endometritis [111 cases (36.51%) in the EP group and 174 patients (47.67%) in the non-EP group], cervical polyps [58 cases (19.08%) in the EP group and 46 cases (12.06%) in the non-EP group], hypertension [48 cases (15.79%) in the EP group and 88 cases (24.11%) in the non-EP group], diabetes mellitus [14 cases (4.61%) in the EP group and 31 cases (8.49%) in the non-EP group] were the risk factors of EP ( Z =-3.71, -4.30, -2.50, χ2 = 4.59, 8.44, 0.02, 0.01, 0.04, all P < 0.05). Multivariate analysis showed that age, number of pregnancies, chronic endometritis and cervical polyps had significant effects on the incidence of EP ( OR = 0.97, 95% CI 0.95-0.99, OR = 0.80, 95% CI 0.72-0.90, OR = 0.53, 95% CI 0.38-0.74, OR = 1.73, 95% CI 1.10-2.72, all P < 0.05). Conclusion:Age, number of pregnancies, chronic endometritis and cervical polyps are all risk factors for the development of endometrial polyps.
ABSTRACT
Resumen ANTECEDENTES: La afectación primaria del aparato genital femenino por un linfoma no Hodgkin es excepcional, se reporta en 0.2 a 1.1% de los casos. Los órganos afectados con más frecuencia son los ovarios, seguidos del cuello uterino; el endometrio y la vagina son los menos aquejados. Debido a su baja frecuencia aún no se llega a un consenso del tratamiento más adecuado de estos linfomas; hasta ahora, por lo general, se ha individualizado para cada caso en concreto. CASO CLÍNICO: Paciente de 29 años que consultó por sangrado genital anómalo e incapacidad para la inserción de tampones vaginales. En la exploración se encontró una masa pélvica, palpable a través de la vagina, que impresionaba al infiltrar toda la luz vaginal y la parte media e izquierda de la vulva. En los estudios de imagen se objetivó una gran masa pélvica de hasta 10 centímetros que parecía depender del cuello del útero y que se extendía e infiltraba el canal vaginal, la vulva y el tercio inferior de la vejiga. El reporte anatomopatológico de la biopsia fue: infiltración de pared vaginal por un linfoma no Hodgkin B difuso de células grandes. Se le indicaron seis ciclos de quimioterapia con ciclofosfamida, vincristina, adriamicina y prednisona con los que se consiguió la remisión metabólica completa. CONCLUSIÓN: El diagnóstico del linfoma genital primario puede resultar complejo por la posibilidad de simular una neoplasia ginecológica. En casos de enfermedad avanzada, la manifestación clínica más frecuente es el sangrado genital anómalo. El esquema de tratamiento más aceptado en la actualidad es con rituximab-ciclofosfamida, vincristina, adriamicina, prednisona seguido de radioterapia de consolidación.
Abstract BACKGROUND: Primary involvement of the female genital tract by non-Hodgkin's lymphoma is exceptional, reported in 0.2 to 1.1% of cases. The most frequently affected organs are the ovaries, followed by the cervix; the endometrium and vagina are the least affected. Due to their low frequency, there is still no consensus on the most appropriate treatment of these lymphomas; until now, it has generally been individualized for each specific case. CLINICAL CASE: A 29-year-old female patient consulted for abnormal genital bleeding and inability to insert vaginal tampons. On examination a pelvic mass was found, palpable through the vagina, which impressed by infiltrating the entire vaginal lumen and the middle and left side of the vulva. Imaging studies showed a large pelvic mass of up to 10 centimeters that appeared to be dependent on the cervix and that extended and infiltrated the vaginal canal, the vulva and the lower third of the bladder. The anatomopathological report of the biopsy was: infiltration of the vaginal wall by diffuse large cell non-Hodgkin's B lymphoma. She was prescribed six cycles of chemotherapy with cyclophosphamide, vincristine, adriamycin and prednisone with which complete metabolic remission was achieved. CONCLUSION: The diagnosis of primary genital lymphoma can be complex because of the possibility of simulating a gynecologic neoplasm. In cases of advanced disease, the most frequent clinical manifestation is abnormal genital bleeding. The most accepted treatment scheme at present is rituximab-cyclophosphamide, vincristine, adriamycin, prednisone followed by consolidation radiotherapy.
ABSTRACT
Resumen INTRODUCCIÓN: El cáncer sincrónico es poco frecuente y de origen incierto. Se caracteriza por diferentes lesiones malignas que afectan dos o más zonas del aparato reproductor al mismo tiempo o en un lapso menor a un año; la combinación ovario y endometrio es la más frecuente. OBJETIVO: Reportar un caso de cáncer ginecológico sincrónico, tumor maligno de células de la granulosa de ovario y carcinoma de células escamosas en la cúpula vaginal; además, revisar la bibliografía al respecto. CASO CLÍNICO: Paciente de 47 años, con histerectomía total por miomatosis y una lesión de gran tamaño que ocupaba el espacio pélvico y comprimía el techo vesical. Acudió a consulta debido a un sangrado genital abundante, pérdida de peso y de orina en forma involuntaria. En el examen físico se evidenció una lesión friable en la cúpula vaginal de 3 cm. Se decidieron la ooforectomía izquierda y la extirpación tumoral. La biopsia y la inmunohistoquímica de las lesiones reportó un tumor maligno de células de la granulosa del adulto localizado en el ovario, y un carcinoma de células escamosas en la cúpula vaginal. Se indicó quimioterapia y en la actualidad la paciente permanece sin recidiva de la enfermedad y en seguimiento oncológico. CONCLUSIÓN: El cáncer sincrónico es poco frecuente, de ahí que se disponga de poca información. Gracias al acierto del diagnóstico y de la conducta terapéutica a seguir, luego de 24 meses la paciente del caso no ha tenido signos de recidiva de la enfermedad; continúa en seguimiento oncológico conforme a los protocolos establecidos.
Abstract INTRODUCTION: Synchronous cancer in gynecology is a rare entity, of uncertain etiology, consisting of different malignant lesions affecting two or more areas of the female reproductive system, at the same time or within a period of less than 1 year, the combination of ovary and endometrium being the most frequent. OBJECTIVE: to report a case of synchronous gynecological cancer, malignant granulosa cell tumor of the ovary and squamous cell carcinoma of the vaginal vault and in view of the infrequency of the case to review the literature. CLINICAL CASE: 47 years old patient, who underwent total hysterectomy for uterine myomatosis plus right oophorectomy for showing ovarian tumor during surgery, the histopathological report reported malignant granulosa cell tumor, abdomino-pelvic tomography was requested, which reported a large pelvic space occupying lesion (LOE) with compression of the bladder roof. She came to our office for the first time due to abundant genital bleeding, weight loss and involuntary urine loss, physical examination revealed a friable lesion in the vaginal vault of 3cm, surgical intervention was decided where a left oophorectomy and tumor pruning were performed, Biopsy and immunohistochemistry of lesions with report of malignant granulosa cell tumor of adult granulosa cells in the ovary and squamous cell carcinoma in the vaginal vault, referred to medical oncology who applied chemotherapy and currently the patient is without recurrence of the disease and in oncological follow-up. CONCLUSION: Synchronous cancer is an infrequent pathology, where much information remains to be investigated to better understand this entity. We present the first reported case of synchronous ovarian granulosa cell tumor cancer with vaginal vault cancer. Fortunately our patient 24 months after completing her treatment shows no signs of recurrence of the disease and will be followed up according to the established oncologic protocols.
ABSTRACT
Resumen INTRODUCCIÓN: Un leiomioma con cambios degenerativos poco frecuentes es un desafío diagnóstico difícil de diferenciar de sus homólogos malignos, si se pretende fundamentarlo solo en lo advertido en las imágenes. CASO CLÍNICO: Paciente de 40 años de edad, enviada al servicio de Cirugía de mínima invasión en marzo del 2021 debido al aumento del perímetro abdominal, disminución del apetito y disnea de medianos esfuerzos. El ultrasonido abdomino-pélvico reportó que el útero estaba aumentado de tamaño, con miomas intramurales de medianos elementos. El endometrio heterogéneo. El ovario derecho tenía un quiste complejo, gigante, de 276 mm x 250 mm x 276 mm, con volumen de 10 000 cc. Además, esplenomegalia, hidronefrosis derecha y litiasis renal izquierda. Los marcadores tumorales se reportaron normales. En la cirugía por laparoscopia se observó un tumor que ocupaba toda la cavidad abdominal de 40 x 30 cm, adherido a la pared posterior del útero, con ambos ovarios sin alteraciones, sin líquido libre; se procedió a la histerectomía total. CONCLUSIONES: Los cambios degenerativos en los leiomiomas uterinos pueden distorsionar la estructura habitual del tumor y reflejarla en imágenes típicas de una tumoración quística de ovario; en el estudio inicial esto representa un desafío para el cirujano y debe considerarse parte del diagnóstico diferencial de las masas anexiales. En la paciente del caso, con cirugía de mínima invasión, se consiguió la resección completa de la pieza, a pesar del tamaño aumentado, con menores riesgos de complicaciones en la herida y menos dolor posoperatorio; las incisiones son pequeñas y con desenlaces estéticos favorables y menos días de estancia intrahospitalaria.
Abstract INTRODUCTION: A leiomyoma with rare degenerative changes is a diagnostic challenge difficult to differentiate from its malignant counterparts, if it is intended to be based only on imaging findings. CLINICAL CASE: 40-year-old female patient referred to the Minimally Invasive Surgery service in March 2021 due to increased abdominal perimeter, decreased appetite and dyspnea on medium exertion. Abdomino-pelvic ultrasound reported that the uterus was enlarged, with medium-element intramural fibroids. The endometrium was heterogeneous. The right ovary had a complex, giant cyst, 276 mm x 250 mm x 276 mm, with a volume of 10,000 cc. In addition, splenomegaly, right hydronephrosis and left renal lithiasis. Tumor markers were reported normal. Laparoscopic surgery showed a tumor occupying the entire abdominal cavity measuring 40 x 30 cm and attached to the posterior wall of the uterus, with both ovaries unaltered, with no free fluid; total hysterectomy was performed. CONCLUSIONS: Degenerative changes in uterine leiomyomas can distort the usual tumor structure and reflect it in images typical of an ovarian cystic tumor; in the initial study this represents a challenge for the surgeon and should be considered part of the differential diagnosis of adnexal masses. In the case patient, with minimally invasive surgery, complete resection of the specimen was achieved, despite the increased size, with less risk of wound complications and less postoperative pain; the incisions are small and with favorable esthetic outcomes and fewer days of in-hospital stay.
ABSTRACT
Introducción. El carcinoma de endometrio es una patología heterogénea a nivel patogénico, histopatológico y molecular.

Introduction. Endometrial carcinoma is a heterogeneous pathology in pathologenic, histopathological, and molecular terms. Over the last years, efforts have been made to clarify and increase knowledge of molecular bases, as such dividing patients into four subgroups described by the The Cancer Genome Atlas (TCGA), obtaining valuable information that affects the diagnosis, treatment, and prognosis of patients with this disease. The objective of this review is to exhibit the new molecular classification of endometrial carcinoma, and to discuss its advantages when stratifying patients and making therapeutic decisions. Division of Covered Topics. A non-systematic bibliographical search was carried out in the PubMed, Cochrane, and Medline databases from 2014 to 2020, on endometrial carcinoma and its molecular classification. The historical context, different molecular subgroups and how these impact patient handling are shown in a concrete and updated way. Conclusions. Endometrial carcinoma is a heterogeneous disease in histopathological, clinical, and molecular terms. With the new classification and the prospective studies, new strategies can be created to provide better diagnostic and therapeutic protocols.

Abstract Objective Abnormalities in the eutopic endometrium of women with endometriosis may be related to disease-associated infertility. Although previous RNA-sequencing analysis did not show differential expression in endometrial transcripts of endometriosis patients, other molecular alterations could impact protein synthesis and endometrial receptivity. Our aim was to screen for functional mutations in the transcripts of eutopic endometria of infertile women with endometriosis and controls during the implantation window. Methods Data from RNA-Sequencing of endometrial biopsies collected during the implantation window from 17 patients (6 infertile women with endometriosis, 6 infertile controls, 5 fertile controls) were analyzed for variant discovery and identification of functional mutations. A targeted study of the alterations found was performed to understand the data into disease's context. Results None of the variants identified was common to other samples within the same group, and no mutation was repeated among patients with endometriosis, infertile and fertile controls. In the endometriosis group, nine predicted deleterious mutations were identified, but only one was previously associated to a clinical condition with no endometrial impact. When crossing the mutated genes with the descriptors endometriosis and/or endometrium, the gene CMKLR1 was associated either with inflammatory response in endometriosis or with endometrial processes for pregnancy establishment. Conclusion Despite no pattern of mutation having been found, we ponder the small sample size and the analysis on RNA-sequencing data. Considering the purpose of the study of screening and the importance of the CMKLR1 gene on endometrial
Resumo Objetivo Anormalidades no endométrio eutópico de mulheres com endometriose podem estar relacionadas à infertilidade associada à doença. Embora a análise prévia de sequenciamento de RNA não tenha evidenciado expressão diferencial em transcritos endometriais de pacientes com endometriose, outras alterações moleculares poderiam afetar a síntese de proteínas e a receptividade endometrial. Nosso objetivo foi rastrear mutações funcionais em transcritos de endométrios eutópicos de mulheres inférteis com endometriose e de controles durante a janela de implantação. Métodos Os dados do sequenciamento de RNA de biópsias endometriais coletados durante a janela de implantação de 17 pacientes (6 mulheres inférteis com endometriose, 6 controles inférteis, 5 controles férteis) foram analisados para a descoberta de variantes e a identificação de mutações funcionais. Um estudo direcionado das alterações encontradas foi realizado para compreender os dados no contexto da doença. Resultados Nenhuma das variantes identificadas foi comuma outras amostras dentro do mesmo grupo, assim como nenhuma mutação se repetiu entre pacientes com endometriose, controles inférteis e férteis. No grupo de endometriose, foram identificadas nove mutações deletérias preditas, mas apenas uma foi previamente associada a uma condição clínica sem impacto endometrial. Ao cruzar os genes mutados com os descritores endometriose e/ou endométrio, o gene CMKLR1 foi associado a resposta inflamatória na endometriose e a processos endometriais para estabelecimento da gravidez. Conclusão Apesar de nenhum padrão de mutação ter sido encontrado, ponderamos o pequeno tamanho da amostra e a análise dos dados de sequenciamento de RNA. Considerando o objetivo do estudo de triagem e a importância do gene CMKLR1 na modulação endometrial, este poderia ser um gene candidato para estudos adicionais que avaliem mutações no endométrio eutópico de pacientes com endometriose.

OBJECTIVES: To compare the effects of low-dose conjugated estrogen (CE), raloxifene, and the combination thereof on the endometrium of postmenopausal women. METHODS: Postmenopausal women between 45 and 60 years of age, with Gail score≥1.67 and no endometrial disorders, were randomly assigned to receive low-dose CE (0.3 mg), raloxifene (60 mg), or combined therapy for 1 year. Transvaginal ultrasound was performed at baseline and every 3 months; the Kupperman Index was assessed at baseline and every 6 months. Endometrial biopsies were performed if endometrial thickness (ET) was ≥5 mm or if vaginal bleeding occurred. The primary outcome was the occurrence of ET≥5 mm over the one-year period. RESULTS: Seventy-three women were randomly assigned and analyzed on an intent-to-treat basis. Eight, three, and four women in the CE, raloxifene, and combination groups, respectively, exhibited ET≥5 mm. No genital bleeding was reported in the combination group. Endometrial biopsy revealed atrophy or polyps in all groups, with one patient in the CE group exhibiting a proliferative endometrium without atypia. At 6 months, there was a progressive increase in mean ET in the CE group, but not in the other two groups, with statistically significant differences at 6, 9, and 12 months. Mean scores for vasomotor symptoms and Kupperman Index favored the CE and combination groups over raloxifene. CONCLUSION: Combined raloxifene and low-dose CE decreased the severity of menopausal symptoms to a similar extent as CE alone and had similar effects as raloxifene alone on the endometrium.
