Leiomyoma of the palatine tonsil - report of a rare and unusual tumor at this site

A leiomyoma is a remarkably rare cause of a benign, one-side tonsillar enlargement. The diagnosis is essentially histologic and will not normally be suspected clinically. Immunohistochemistry is needed for substantiation of the morphology and confirmation. We submit this illustrative case report.

Importância do diagnóstico por imagem em pacientes com sangramento uterino anormal / Importance of diagnostic imaging in patients with abnormal uterine bleeding

O sangramento uterino anormal é diagnóstico sindrômico comum no consultório do ginecologista e pode comprometer substancialmente a qualidade de vida. O objetivo no diagnóstico de sangramento uterino anormal é distinguir pacientes com causas estruturais (anatômicas), como pólipo, adenomiose, leiomioma, malignidade e hiperplasia, de pacientes que apresentam anatomia normal, nas quais o sangramento pode ser devido a alteração dos mecanismos de coagulação, distúrbios ovulatórios, distúrbios primários do endométrio, iatrogenia, ou ter outra causa não classificada. O diagnóstico se inicia a partir de anamnese detalhada e exame físico geral e ginecológico completos, seguidos da solicitação de exames complementares (laboratoriais e de imagem), conforme indicado. O exame de imagem de primeira linha para identificação das causas estruturais inclui a ultrassonografia pélvica. Histerossonografia, histeroscopia, ressonância magnética e amostragem endometrial para exame de anatomia patológica são opções que podem ser incluídas no diagnóstico a depender da necessidade. O objetivo deste artigo é apresentar a relevância dos exames de imagem na investigação das causas de sangramento uterino anormal.

Abnormal uterine bleeding is one of the commonest presenting complaints encountered in a gynecologist's office and may substantially affect quality of life. The aim in the diagnosis of abnormal uterine bleeding is to distinguish women with anatomic causes such as polyp, adenomyosis, leiomyoma, malignancy and hyperplasia from women with normal anatomy where the cause may be coagulopathy, ovulatory disorders, endometrial, iatrogenic and not otherwise classified. Diagnosis begins with a thorough history and physical examination followed by appropriate laboratory and imaging tests as indicated. The primary imaging test for the identification of anatomic causes include ultrasonography. Saline infusion sonohysterography, magnetic resonance, hysteroscopy, endometrial sampling are options that can be included in the diagnosis depending on the need. The aim of this article is to present the relevance of imaging exams in the investigation of the causes of abnormal uterine bleeding.

Expression and sensitivity of immunohistochemical markers SMA, Desmin, CD10 for uterine leiomyomas - A tertiary care centre experience

Introduction: Leiomyoma is the most common benign tumor of the uterus which usually presents with menorrhagia, pain in abdomen or both. In extremely rare cases where uterine leiomyoma can be difficult to distinguish from other uterine smooth muscle tumors, immunohistochemistry is used. This study was aimed to study the expression and sensitivity of immunohistochemical markers SMA, Desmin, CD 10 for uterine leiomyomas and to find average number of mitosis in uterine leiomyomas using Ki 67. Materials and methods: The present study was carried out in the Department of Pathology, Dhiraj General Hospital and Smt. Bhikhiben Kanjibhai Shah Medical Institute and Research Centre, Sumandeep Vidyapeeth, Piparia. A total 50 cases of uterine leiomyomas after its histological diagnosis were evaluated with immunohistochemical markers SMA, Desmin, CD 10 and Ki 67. Results: SMA expression was seen in all 50 cases of uterine leiomyomas with strong expression in 44 cases (88%). Strong SMA expression was seen more in usual leiomyomas as compared to leiomyomas with secondary changes. Desmin expression was also seen in all the 50 cases of uterine leiomyomas with moderate expression in 26 cases (52%). Weak CD 10 expression was seen in 15 cases of uterine leiomyomas (30%). Ki 67 was expressed very focally in only 3 cases of leiomyomas with mean value of only 0.3% tumor cells. Conclusions: Leimyomas was most frequently seen in the women in 4th decade. The most common clinical presentation was menorrhagia. SMA and Desmin expression was seen in all the cases with strong and moderate immunoreactivity respectively. SMA expression was found to be more specific than Desmin in uterine leiomyoma. Weak CD 10 and focal Ki 67 were expressed only in few cases and were found to be insignificant.

Leiomioma ovárico primario

El leiomioma es un tumor mesenquimal benigno común que puede desarrollarse allí donde haya músculo liso; raro como tumor ovárico primario, su origen aún es controversial. El leiomioma ovárico primario es uno de los tumores benignos más raros del ovario, representa 0,5% a 1% de los tumores benignos y suele observase en mujeres entre 20 y 65 años. Generalmente, son asintomáticos y se les encuentra de forma incidental durante el examen pélvico o la cirugía por otra causa, pero en ocasiones puede manifestarse por dolor abdominal y masa palpable. El diagnóstico definitivo es difícil antes de la extirpación quirúrgica. Debido a que no existen síntomas patognomónicos ni tiene imágenes características, los principales diagnósticos diferenciales incluyen fibroma, tecoma, tumor estromal esclerosante y leiomiosarcoma. La tinción inmunohistoquímica es fundamental para el diagnóstico preciso y debe considerarse en el diagnóstico diferencial de los tumores ováricos de células fusiformes. Se presenta un caso de leiomioma ovárico primario.

Leiomyoma is a common benign mesenchymal tumor that can develop wherever smooth muscle is present; rare as a primary ovarian tumor, its origin is still controversial. Primary ovarian leiomyoma is one of the rarest benign ovarian tumors, accounting for 0.5% 1% of benign tumors and is usually seen in women between 20 and 65 years of age. They are usually asymptomatic and appear incidentally during a pelvic examination or surgery for another cause but can occasionally manifest by abdominal pain and palpable mass. Definitive diagnosis is difficult before surgical removal. Because there are no pathognomonic symptoms and no characteristic imaging, the main differential diagnoses include fibroma, thecoma, sclerosing stromal tumor and leiomyosarcoma. Immunohistochemical staining is essential for accurate diagnosis and should be considered in the differential diagnosis of ovarian spindle cell tumors. A case of primary ovarian leiomyoma is presented.

Reporting of uterine fibroids on ultrasound examinations: an illustrated report template focused on surgical planning / Relato de miomas uterinos em exames de ultrassonografia: um modelo de relatório ilustrado com foco no planejamento cirúrgico

Abstract Uterine fibroids are the most common benign gynecologic tumors in women of reproductive age, and ultrasound is the first-line imaging modality for their diagnosis and characterization. The International Federation of Gynecology and Obstetrics developed a system for describing and classifying uterine fibroids uniformly and consistently. An accurate description of fibroids in the ultrasound report is essential for planning surgical treatment and preventing complications. In this article, we review the ultrasound findings of fibroids, detailing the main points to be reported for preoperative evaluation. In addition, we propose a structured, illustrated report template to describe fibroids, based on the critical points for surgical planning.

Resumo Os miomas uterinos são os tumores ginecológicos benignos mais comuns em mulheres em idade reprodutiva, sendo a ultrassonografia a modalidade de imagem de primeira linha para seu diagnóstico e caracterização. A Federação Internacional de Ginecologia e Obstetrícia desenvolveu um sistema para descrever e classificar os miomas uterinos de forma uniforme e consistente. Uma descrição precisa dos miomas no laudo ultrassonográfico é essencial para o planejamento do tratamento cirúrgico e prevenção de complicações. Neste artigo, revisamos os achados ultrassonográficos de miomas, detalhando os principais pontos a serem relatados para avaliação pré-operatória. Além disso, propomos um modelo de relatório estruturado e ilustrado para descrição de miomas, com base nos pontos críticos para o planejamento cirúrgico.

The value of CT for differentiating gastric leiomyoma from gastric schwannoma / 中国医师进修杂志

Objective:To evaluate the value of CT for differentiating gastric leiomyoma (GLM) from gastric schwannoma (GS).Methods:The clinical and imaging data of 42 patients with GLM (GLM group) and 41 patients with GS (GS group) were analyzed retrospectively. The general information and CT features were compared between two groups. The independent factors for differentiating GLM from GS were obtained by multivariate Logistic regression analysis. The receiver operating characteristic curve (ROC) was used to evaluate the diagnostic efficiency of the model.Results:The proportion of female and age in GLM group were significantly lower than those in GS group: 59.52% (25/42) vs. 85.37% (35/41), (51.83 ± 10.52) years old vs. (58.80 ± 10.63) years old, and there were statistical differences ( P<0.01). The upper part of the stomach rate, irregular shape rate, intraluminal growth rate, ratio of long diameter to short diameter and mild to moderate enhancement rate in GLM group were significantly higher than those in GS group: 71.43% (30/42) vs. 14.63% (6/41), 52.38% (22/42) vs. 21.95% (9/41), 92.86% (39/42) vs. 19.51% (8/41), 1.90 ± 0.55 vs. 1.34 ± 0.28 and 92.86% (39/42) vs. 51.22% (21/41), the cystic degeneration rate, ulcer rate, incidence of tumor-associated lymph node, CT values of venous phase and delayed phase in GLM group were significantly lower than those in GS group: 2.38% (1/42) vs. 26.83% (11/41), 7.14% (3/42) vs. 24.39% (10/41), 2.38% (1/42) vs. 60.98% (25/41), (59.21 ± 9.75) HU vs. (66.22 ± 10.33) HU and (65.02 ± 8.62) HU vs. (76.85 ± 11.89) HU, and there were statistical differences ( P<0.01 or <0.05); there were no statistical difference in the rate of calcification and the CT values of plain scan and arterial phase between the two groups ( P>0.05). Multivariate Logistic regression analysis result showed that the tumor location, growth mode, tumor-associated lymph node and ratio of long diameter to short diameter were the independent factors for differentiating GLM from GS ( OR = 34.385, 25.314, 0.023 and 97.700; 95% CI 2.848 to 415.171, 2.674 to 239.670, 0.001 to 0.637 and 3.113 to 3 066.549; P<0.01 or <0.05); when the model threshold was >0.647, the area under the curve was 0.988 (95% CI 0.934 to 1.000), with a sensitivity of 92.9% and specificity of 97.6%. Conclusions:When the tumor is prone to the upper part of the stomach, intraluminal growth, ratio of long diameter to short diameter >1.28, and the absence of the tumor-associated lymph node, GLM tends to be considered, on the contrary, it tends to be GS. Therefore, CT imaging features have certain value in differentiating GLM from GS before surgery.

Torsión uterina causada por miomatosis: reporte de un caso / Uterine torsion caused by myomatosis: A case report

Resumen ANTECEDENTES: La torsión uterina es una rotación del útero sobre su eje mayor de más de 45°; por lo general sucede en torno del istmo uterino. Los leiomiomas son el factor predisponente más frecuente en úteros no grávidos. OBJETIVO: Reportar el caso de una paciente con torsión uterina cervical y miomatosis de grandes elementos. CASO CLÍNICO: Paciente de 42 años, nuligesta, con antecedente de miomatosis uterina de grandes elementos de 27 x 27 cm. Los síntomas se iniciaron con síndrome doloroso abdominal intenso, tipo cólico, localizado en el hipogastrio y la fosa iliaca. En la exploración física el abdomen se percibió doloroso a la palpación superficial y profunda, con una tumoración cercana a la cicatriz umbilical (25 cm), móvil y dolorosa. En la laparotomía exploradora se encontró líquido peritoneal hemorrágico y se observó una torsión uterina (una vuelta) cerca del cuello del útero, además de un mioma subseroso en la cara posterior, de 27 x 27 cm. El útero, los anexos y las salpinges se advirtieron con datos francos de daño vascular, con áreas de isquemia. Por lo anterior se decidieron la histerectomía total abdominal y la salpingooforectomia bilateral. El informe histopatológico reportó: útero con cambio isquémico extenso panmural, sin evidencia de neoplasia maligna. CONCLUSIONES: El dolor abdominal es el síntoma más común de la torsión uterina que puede variar de leve a agudo. El diagnóstico preoperatorio rápido y preciso de torsión uterina es decisivo y se justifica la intervención quirúrgica de urgencia.

Abstract BACKGROUND: Uterine torsion is a rare entity that is defined as a rotation of the uterus on its major axis of more than 45°, generally occurring at the level of the uterine isthmus. Leiomyomas are the most frequent predisposing factor in non-gravid uterus. OBJECTIVE: Report of a case of a gynecological patient with uterine torsion at the cervical level in a uterus with uterine myomatosis of large elements. CLINICAL CASE: A 42-year-old patient, nulliparous, with a history of uterine myomatosis with large elements of 27 x 27 cm. The symptoms began with intense abdominal pain syndrome, colic type, located in the hypogastrium and the iliac fossa. On physical examination, the abdomen was perceived as painful on superficial and deep palpation, with a mobile and painful tumor close to the umbilical scar (25 cm). In the exploratory laparotomy, hemorrhagic peritoneal fluid was found and a uterine torsion (one turn) was observed near the cervix, as well as a subserous myoma on the posterior face, measuring 27 x 27 cm. The uterus, the annexes and the salpinges were noted with frank data of vascular damage, with areas of ischemia. Therefore, total abdominal hysterectomy and bilateral salpingo-oophorectomy were decided. The histopathological report reported: uterus with extensive panmural ischemic change, without evidence of malignancy. CONCLUSIONS: In uterine torsion, abdominal pain is the most common symptom and can range from mild to severe abdominal symptoms. Therefore, a prompt and accurate preoperative diagnosis of uterine torsion is crucial and urgent surgical intervention is warranted.

Diagnosis and treatment of 12 cases of fumarate hydratase-deficient renal cell carcinoma / 现代泌尿外科杂志

【Objective】 To summarize and analyze the clinical data of fumarate hydrase-deficient renal cell carcinoma (FH-RCC), so as to improve the understanding of the disease. 【Methods】 General clinical data of 12 FH-RCC patients treated during Mar.2019 and Dec.2021 were retrospectively analyzed, including the imaging, pathological, genetic testing, surgical and adjuvant therapy, and follow-up results. 【Results】 All cases were confirmed with pathology or genetic tests, including 1 case complicated with uterine fibroids, 3 cases with renal cysts, 4 with family history of uterine fibroids and 2 with family history of renal carcinoma. Cysticular irregular density shadows with an enhancement of 25.8 Hu were detected in 4 cases. Of the 7 cases undergoing genetic testing, 2 had embryo and system mutation, 1 had germ line mutation, 1 had system mutation, and 3 had no germ line or system mutation. Radical nephrotomy was performed in 9 cases. The average operation time was 3.8 h, and the average amount of blood loss was 625 mL. Immunotherapy with targeted therapy was conducted in 10 cases, surgery with postoperative adjuvant therapy in 7 cases, and tyrosine kinase inhibitor with immune checkpoint inhibitor (TKI/ICI) in 1 case. All 12 cases were followed up, 3 died of tumor, 1 had no recurrence, 8 showed progress on imaging. 【Conclusion】 FH-RCC is a rare and highly malignancy prone to metastasis. Imaging shows cystic solid space occupying lesions. FH immunohistochemical staining is negative. Genetic testing is needed to confirm the diagnosis. TKI/ICI combination therapy has a good survival benefit.

Uterine Epithelioid Leiomyosarcoma Arising Within Leiomyoma in A Postmenopausal Woman: A Case Report

@#Uterine leiomyosarcoma is a malignant smooth muscle tumour of the uterus. It is rare and accounting for less than 2% of cases in malignant gynaepathology. To date, only a few reported cases of leiomyosarcoma arising from leiomyoma documented in the literature. We shared an uncommon occurrence of leiomyosarcoma arising from leiomyoma. Presented herein is a case of a ‘rare epithelioid subtype’ of leiomyosarcoma arising from a leiomyoma in a postmenopausal woman. We highlighted the importance of recognizing the possibilities of this event to allow for a timely diagnosis of leiomyosarcoma and to provide insights on management of patients presented with clinically presumed fibroid.

Leiomyomas are benign tumors that arise from smooth muscle cells and rarely involve the male genitourinary system. We reported a case of a patient who underwent radical orchiectomy for epididymal tumor. The postoperative pathological diagnosis was epididymal leiomyoma, and there was no recurrence after 9 months of follow-up.

Safety and effectiveness of superselective embolization of the uterine arteries in the treatment of uterine fibroids / 中国基层医药

Objective:To analyze the safety and effectiveness of superselective embolization of the uterine arteries in the treatment of uterine fibroids.Methods:The clinical data of 60 patients with uterine fibroids who were admitted to Zhejiang Veteran Hospital from February 2020 to February 2022 were retrospectively analyzed. These patients were divided into a control group and an observation group ( n = 30/group) according to different surgical methods. The control group underwent conventional surgery. The observation group underwent superselective embolization of the uterine arteries. Uterine size, uterine fibroid size, postoperative hormone level, and complications were compared between the two groups. Results:There was no significant difference in total response rate between the observation and control groups [93.33 (28/30) vs. 83.33 (25/30), χ2 = 1.46, P > 0.05]. After surgery, serum estradiol, luteinizing hormone, follicle-stimulating hormone, and progesterone levels in the observation group were (164.14 ± 19.97) ng/L, (2.43 ± 1.47) IU/L, (2.51 ± 1.14) IU/L, and (5.05 ± 0.43) μg/L, respectively, which were significantly lower than (190.23 ± 21.62) ng/L, (3.78 ± 1.63) IU/L, (3.94 ± 1.23) IU/L, (8.22 ± 1.35) μg/L in the control group ( t = 4.86, 3.37, 4.67, 12.25, all P < 0.05). The incidence of postoperative complications in the observation group was significantly lower than that in the control group [3.33% (1/30) vs. 20.00% (6/30), χ2 = 4.04, P < 0.05). Conclusion:Compared with conventional surgery, superselective embolization of the uterine arteries is more effective on uterine fibroids, better keep postoperative hormone level stable, and reduce or avoid short- and long-term complications. Therefore, superselective embolization of the uterine arteries for the treatment of uterine fibroids deserves the clinical promotion.

Leiomioma submucoso de gran tamaño: una presentación inusual. Reporte de Caso / Large submucosal leiomyoma: an unusual presentation

Se ha postulado que más del 70 % de las mujeres antes de la menopausia son diagnosticadas de leiomiomas; de estas un 25 % presentan sintomatología grave. La ecografía es la modalidad de imagen de primera elección para su estudio. Se tiene registros de progresión de leiomiomas a leiomiosarcomas, que conllevan a un mal pronóstico y son responsables de una cuarta parte de las muertes por neoplasias uterinas, con una sobrevida a 5 años que van desde 46-53 %, lo cual incentiva el diagnóstico precoz y eficaz de masas uterinas. El caso reportado es una presentación inusual de un leiomioma de gran tamaño, que por los hallazgos de imagen se reportó como una neoplasia maligna, su aspecto macroscópico totalmente atípico reforzaba la sospecha imagenológica. Solo se pudo determinar el diagnóstico definitivo mediante estudio histopatológico posterior a histerectomía. Las evaluaciones ginecológicas de rutina deben incluir exámenes especializados de imagen pélvica, la ausencia de presentación típica o síntomas característicos de una patología no debe ser motivo para obviar exámenes complementarios que permitan un diagnóstico oportuno y tratamiento eficiente de leiomiomas, incluso en casos de presentaciones inusuales y desafiantes para el diagnóstico, como el que se ha reportado en esta obra.

It has been postulated that more than 70% of premenopausal women are diagnosed with leiomyomas; Of these, 25% have severe symptoms. Ultrasound is the imaging modality of choice for its study. There are reports of progression from leiomyomas to leiomyosarcomas, which leads to a poor prognosis, and is responsible for a quarter of deaths from uterine neoplasms, with a 5-year survival ranging from 46-53%; this should encourage early and effective diagnosis of uterine masses. The reported case is an unusual presentation of a large leiomyoma, which due to its imaging characteristics, was reported as a malignant neoplasm. Its completely atypical macroscopic appearance reinforced the imaging diagnosis suspicion. The definitive diagnosis could only be determined by histopathological study after hysterectomy. Routine gynecological evaluations should include specialized pelvic imaging exams, the absence of a typical presentation or characteristic symptoms of a pathology should not be a reason to obviate ancillary testing that would allow a timely diagnosis and effective treatment of leiomyomas, even in unusual and challenging presentations, such as with the patient in this case report.

Histopathological analysis of hysterectomy specimens

Background: Uterus is prone for various non-neoplastic and neoplastic lesions and also hysterectomy is the most common gynecological surgery indicated as a definitive treatment. Grossly unremarkable many specimens may reveal pathologies on histological examination. Hence, all hysterectomy specimens must undergo proper histopathological examination. In our study, hysterectomy specimens were studied and results compared with their clinical diagnosis. Aim and Objective: The objectives of the present study were to know the frequency and incidence of various lesions of the female genital tract and to compare findings of the present study with other studies. Materials and Methods: The study was a retrospective analysis of 250 hysterectomy specimens. All types of hysterectomies such as vaginal, abdominal, laparoscopic, and total abdominal hysterectomy without or with unilateral/bilateral salpingectomy/salpingo-oophorectomy were included in the study. Histopathological examination was done minimum by two faculty members. The results were noted and statistical analysis was done. Results: Total 250 hysterectomy specimens were studied. Vaginal hysterectomy was the most commonly performed type of hysterectomy which includes 187 cases (74.8%) out of 250 cases. Among the uterine pathologies, the most common lesion was leiomyoma (34.4%) followed by adenomyosis (26%). In our study during histopathological examination of cervix, the most frequent cervical lesion was found chronic cervicitis in 50.4% of cases. Conclusion: The present study highlights the wide spectrum of lesions of female genital tract and conveys that histopathology remains the primary modality for confirmation of diagnosis of lesions. We can conclude from the present study that many lesions had been diagnosed on microscopic examination though normal gross examination. Hysterectomy specimen should undergo proper histopathological examination, because it is the gold standard tool for final diagnosis.

Histological Variants of Leiomyoma: A Great Impersonator posing a Diagnostic Challenge - Three year Study in Delhi NCR

Background: Objectives: Uterine smooth muscle tumours are diagnostically challenging as well as scientifically intriguing with leiomyoma being the most common. On review of literature there are numerous studies on audit of hysterectomy specimens worldwide, however, studies focusing on detailed histopathologi cal analysis of leiomyomas are limited. Thereby, this study was conducted to identify the secondary changes as well as histological variants of leiomyoma, their frequency of occurrence and other associated clinicopathological factors Methods: A retrospecti ve audit of all the hysterectomy and myomectomy specimens was conducted over a period of 3 years (Jan 2016 to Dec 2018) comprising of a total of 155 cases with 388 leiomyomas (LM). The clinical details were retrieved, and histopathological slides reviewed for cellularity, mitosis, atypia, necrosis, any secondary changes or specific variants. Results: On histopathology, 19.1% LM showed degenerative changes and histologic variants were observed in 6.18% LM. Hyaline change was the most frequent degenerative ph enomenon in 82.43% (60/74) while cellular leiomyoma was the most common variant in 37.5% (9/24) LM. Conclusion: Certain histological variants make the differentiation from malignant tumors challenging. A thorough tissue sampling and strict adherence to histologic criteria coupled with a ncillary techniques like immunohistochemistry can help in excluding malignancy in most of the cases. Awareness regarding these is very important amongst youn g pathologists to avoid misdiagnosis and overtreatment leading to unwarranted stress to the patient.

Uterine artery embolization with highly compressible calibrated microspheres for the treatment of uterine fibroids / Embolização de miomas uterinos com microesferas calibradas de alta compressibilidade

Abstract Objective: To evaluate the safety and efficacy of using highly compressible calibrated microspheres in uterine artery embolization (UAE) for the treatment of uterine fibroids. Materials and Methods: This was a prospective multicenter study. Thirty-two women with symptomatic uterine fibroids were selected for UAE between January 2019 and March 2020. The participants completed the Uterine Fibroid Symptom and Quality of Life (UFS-QOL) questionnaire, underwent contrast-enhanced pelvic magnetic resonance imaging (MRI), and were submitted to anti-Müllerian hormone measurement, subsequently undergoing UAE with Embosoft microspheres. After six months, the patients again completed the UFS-QOL questionnaire and underwent pelvic MRI. Results: The most common symptoms were abnormal uterine bleeding (in 81.3% of the cases), pelvic pain (in 81.3%), and compression (in 46.9%). Of the 32 patients evaluated, 12 (37.5%) had anemia due to abnormal uterine bleeding. Thirty patients completed the study. Among those patients, we observed median reductions of 21.4% in uterine volume and 15.9% in dominant fibroid volume. We identified no adverse events that could be attributed to the material itself, although there were events attributed to the UAE procedure in general. Conclusion: For the treatment of uterine fibroids, UAE using Embosoft microspheres shows satisfactory results, providing reductions in uterine and dominant fibroid volumes, with a low rate of adverse events, and improving patient quality of life, as well as demonstrating safety and efficacy.

To study the histomorphological spectrum of uterine leiomyoma variants. This study is done over a period of three year (May 2019 to May 2022) in the Department of Pathology, LNMC, Bhopal. Total of 316 hysterectomy and 14 myomectomy specimens were studied. Specimens were fixed in formalin and paraffin embedded. H&E stained tissue sections were studied. In the study we performed retrospective analysis of hysterectomy and myomectomy specimen and 330 cases of leiomyoma were evaluated. Among 330 cases, 316(95.75%) were hysterectomy specimen for varying indication and 14(4.24%) were myomectomy specimen. Histologically the usual leiomyomas was comprising of 164(49.69%) cases followed by hyalinised leiomyoma 70(21.21%), myxoid leiomyoma 15(4.54%), hydropic change 12(3.63%), cellular 11(3.33%), lipoleiomyoma 10(3.03%), calcification 10(3.03%), infarct type necrosis 10(3.03%), mitotically active 8(2.42%), symplastic 7 (2.12%), schwanonian 6(1.81%), epithelioid 3(0.90%), dissecting leiomyoma 2 (0.60%) and stromal metaplasia (osseous and cartilaginous) 2(0.60%). Leiomyoma is the commonest benign smooth muscle tumor of the uterus with a number of histological variants. In this study conventional leiomyoma being the commonest variant followed by hyalinized leiomyoma, myxoid leiomyoma, hydropic leiomyoma and lipoleiomyoma. It is important to categorise various types of leiomyoma on histology to avoid misdiagnosis.

Urethral leiomyoma: combined vaginal and abdominal approach - a case report / Mioma uretral: abordagem combinada vaginal e abdominal - um relato de caso

Abstract Introduction: leiomyomas are benign mesenchymal tumors of smooth muscle origin that can develop in various locations. Urethral leiomyomas are rare, with approximately only 120 cases reported in the literature. These tumors often occur in the third and fourth decades of life but are rare in menopausal patients. In general, treatment involves surgery, only three recurrence reports in the literature. Description: a case report on a 56-year-old woman; the patient had type II diabetes mellitus and chronic high blood pressure, was overweight (body mass index, 27.1 kg/m2), and a smoker. Besides this, the patient presented symptoms of urinary obstruction and had a large urethral leiomyoma. The tumor was completely removed with no associated urethral lesions using a complex, combined abdominalvaginal surgical approach. Discussion: the management and treatment on urethral leiomyomas is challenging and have not been established yet due to the rarity of these tumors.

Angioleiomioma en cavidad oral «una neoplasia rara en un sitio poco común¼. Reporte de un caso y revisión de la literatura / Angioleiomyoma in the oral cavity «a rare neoplasm in an unusual site¼. Case report and literature review

El angioleiomioma (AL) es una neoplasia benigna, bien circunscrita y de crecimiento lento, que representa 5% de las neoplasias de tejidos blandos y cuya etiología es desconocida. Se origina del músculo liso, mayormente de las paredes de los vasos sanguíneos; su localización es más frecuente en extremidades, siendo raros en la región de cabeza y cuello, y más aún en cavidad bucal. Histológicamente la lesión se caracteriza por ser un nódulo bien encapsulado con proliferación de fascículos de músculo liso maduro alrededor de la luz de los vasos sanguíneos, cuyas células suelen ser positivas a marcadores de inmunohistoquímica como alfa actina de músculo liso, desmina, HHF35, miosina, calponina y H-caldesmon. El tratamiento actual es la escisión quirúrgica completa con una tasa de recurrencia prácticamente nula. El objetivo es resaltar la importancia del diagnóstico y el manejo correcto de las lesiones intraorales a través de la presentación de un caso clínico de un leiomioma vascular localizado en región nasolabial, además de hacer la revisión de la literatura correspondiente (AU)

The angioleiomyoma (AL) is a benign neoplasm, well circumscribed and slow growing, that represents 5% of the soft tissue neoplasms, whose etiology is unknown. It originates from smooth muscle, mostly from the walls of blood vessels; regarding its location, it more frequently appears in the extremities, being rare in the head and neck region, and even more so in the oral cavity. Histologically, the lesion is characterized by being a well encapsulated nodule with proliferation of mature smooth muscle bundles around the lumen of the blood vessels, whose cells are usually positive for immunohistochemical markers such as alpha smooth muscle actin, desmin, HHF35, myosin, calponin and H-caldesmon. The current treatment is complete surgical excision having zero recurrence rate. The objective of the following article is to educate on the importance of correct diagnosis and management of intraoral lesions through the presentation of a clinical case of a vascular leiomyoma located in the nasolabial region, in addition to reviewing the corresponding literature (AU)

Leiomioma disecante cotiledóneo del útero / Cotyledonoid dissecting leiomyoma of the uterus

RESUMEN Los tumores benignos de músculo liso son los tumores más frecuentes en el aparato genital femenino. El leiomioma disecante cotiledóneo del útero es una variante rara de leiomioma benigno, que presenta patrones de crecimiento inusuales y comparte algunas características con otras variantes de leiomioma disecante. Tiene un patrón de crecimiento inusual caracterizado por disección intramural dentro del miometrio y con apariencia similar de sus componentes extrauterinos a los cotiledones placentarios. Su aspecto sarcomatoide y carácter inusual dan la impresión de malignidad. El diagnóstico se realiza por los hallazgos histopatológicos característicos de la lesión. Se presenta un caso de leiomioma disecante cotiledóneo del útero.

ABSTRACT Benign smooth muscle tumors are the most common tumors in the female genital tract. Cotyledonoid dissecting leiomyoma of the uterus is a rare variant of benign leiomyoma, which presents unusual growth patterns and shares some features with other variants of dissecting leiomyoma. It has an unusual growth pattern characterized by intramural dissection within the myometrium and with similar appearance of its extrauterine components to placental cotyledons. Its sarcomatoid appearance and unusual character give the impression of malignancy. The diagnosis is made by the characteristic histopathologic findings of the lesion. A case of cotyledonoid dissecting leiomyoma of the uterus is presented.
