Simultaneous Endometrial Cancer with Extensive Pelvic and Vulvar Endometriosis: A Case Report.

Background: Endometrial cancer represents the most prevalent malignant genital tract neoplasm in high-income countries and is the second most common cancer worldwide following cervical cancer. Endometriosis is a benign condition wherein endometrial glands and stroma are found outside the uterine cavity. Case Presentation: During a routine care and ultrasound examination of the uterus and adnexa of a 64-year-old woman, an increased endometrial thickness (22 mm) was noted. In 2023, according to ultrasound report, the patient underwent diagnostic curettage with immunohistochemistry, revealing a pathological diagnosis of endometrial cancer (endometrioid adenocarcinoma) with positive staining for p16, estrogen receptor (ER), and vimentin. Subsequently, after one week, she underwent complete surgical staging. Extensive superficial endometriosis disseminated in the pelvis and vulva was noted during surgery and preoperative examinations. Final pathology confirmed a well-differentiated typical endometrioid carcinoma (grade 1) with 40% myometrial invasion and positive lymphovascular invasion. The patient was considered to be at stage 1A. Conclusion: Despite some studies suggesting an unclear association between endometriosis and endometrioid or clear-cell ovarian cancers, the correlation between endometriosis and endometrial cancer and its prognosis remains ambiguous. Additionally, although infertility has been linked to both endometrial cancer and endometriosis in various studies, the presented case exhibited no signs of infertility. Extensive pelvic endometriosis with vulvar involvement was present, yet the patient did not exhibit any symptoms. This is in contrast to the typical initial manifestation of endometrial cancer, which is abnormal uterine bleeding. The patient's condition was incidentally detected through routine care due to an abnormal increase in endometrial thickness, prompting this presentation.

Unexpectedly large myoepithelioma-like tumor of the vulvar region with two local recurrences: A rare case report and review of the literature.

Myoepithelioma-like tumors of the vulvar region (MELTVR) are rare. Only a limited number of MELTVRs are reported in the literature, and various aspects of this lesion still need to be clarified. In this study, we reported a case of MELTVR in a 46-year-old female. The uniqueness of the present case was its large size (12 cm) compared to the MELTVRs reported in earlier studies, the presence of two separate but attached lesions (one in labia majora and one in the mons pubis), and two recurrences within ten years after wide local excision. The second recurrence was managed with wide excision, and the patient remained disease-free during the two-year follow-up. This case highlights the local aggressiveness of MELTVR and the necessity of resection with an adequate margin. It also urges more awareness regarding the differential diagnosis of MELTVR with other lesions of the vulva, particularly when located in the labia majora and mons pubis.

Epithelioid Inflammatory Myofibroblastic Sarcoma With Poor Response to Crizotinib: A Case Report.

Introduction: Epithelioid type inflammatory myofibroblastic sarcoma (EIMS) is a subtype of inflammatory myofibroblastic tumor (IMT). It consists of round or epithelioid cells, and almost all types of EIMS contain rearrangements of the anaplastic lymphoma kinase (ALK) gene. Case presentation: We describe a 20-year-old female presenting with abdominal pain and a rapidly growing intraabdominal mass who underwent surgical tumor resection. She was diagnosed with EIMS. ALK and ki-67 expressions were detected in immunohistochemistry assessment. She was started with Crizotinib 200 mg twice a day, and chemotherapy was also initiated due to the recurrence of the disease 4 months after the initial treatment. She was unresponsive to all the medical regimens and died in 8 months. Conclusion: Approach to patients with EIMS is really challenging in terms of both diagnosis and treatment. Patients with combined surgical and non-surgical treatment regimen were seen to have a more favorable outcome in some EIMS cases. Therefore, it is essential to implement a multidisciplinary approach to diagnose and treat patients suspicious of EIMS.

Second recurrence of aggressive vulvar angiomyxoma: a case report.

Aggressive angiomyxoma is a rare benign tumor with diverse clinical and radiologic presentations, making its differential diagnosis challenging. Here we report the second recurrence of an aggressive angiomyxoma of the vulva in a 33-year-old woman who presented with pain and swelling. Clinical examination revealed a well-circumscribed large palpable mass extending from the inferior part of the right labia major into the right side of the gluteus. A second recurrence of aggressive angiomyxoma was suspected based on the patient's history, clinical examination, and magnetic resonance imaging report, and the patient underwent surgical resection with a negative margin. Histological evaluation of the extracted lesion confirmed the diagnosis of aggressive angiomyxoma. At the 1-year follow-up, the patient was recurrence-free. The present report urges more awareness regarding the aggressiveness of angiomyxoma of the vulva. Closer attention should be given to margin-free removal of such tumors, and patients should be routinely followed up for at least 2 years postoperatively for early diagnosis of recurrence, thereby reducing the risk of morbidity.

PTEN promoter methylation and expression in endometrial cancer tissues.

Introduction: Some gene expression regulation in cancers can be controlled by epigenetic change like methylation. PTEN promoter methylation and expression were evaluated in endometrial cancer. Methods: The study was run on 39 tumor tissues of endometrial cancer patients and 41 normal endometrial tissues. After total RNA extraction, cDNA synthesis was done by reverse transcription of the total (real-time PCR) using SYBER Green master mix. DNA extraction and bisulfite treatment were conducted and methylation was semiquantified by the methylation-sensitive high-resolution melting method. Finally, promoter methylation quantification of the total number of 25 tumors and 22 non-neoplastic tissues was done. Results: PTEN gene expression showed a significant decrease in endometrial cancer tissues. Promoter methylation was significantly lower in the non-neoplastic group (7.2; p < 0.001). In addition, PTEN promoter methylation was observed in 52.0% of tumor tissues compared with 13.6% in the non-neoplastic group (p = 0.06). There were no significant correlations between PTEN expression and methylation and clinicopathological features in endometrial cancer patients (p > 0.05). Conclusion: PTEN gene expression in endometrial cancer tissues decreased because of its promoter hypermethylation.

PEComa-A Rare Uterine Neoplasm: A Case Report.

Background: Perivascular Epithelioid Cell Tumors (PEComas) are rare mesenchymal tumors originating from perivascular epithelioid cells. The second common affected organ is uterine. Most of PEComas are benign and patients have good prognosis. At the present time, surgery is the main treatment and adjuvant chemotherapy is used in malignant cases, although the best diagnostic and management method is yet to be discovered considering the rarity of this neoplasm. Case Presentation: The patient was a 53 year old lady with a history of two vaginal deliveries and no previous surgery. She had severe pelvic pain and underwent MRI with the primary impression of sarcoma. In MRI, she had a 7 cm mass in lower segment of uterus. The patient underwent laparoscopic hysterectomy, bilateral oophorectomy, lymphadenectomy, and omental biopsy in Jam Hospital. Pathologic report of the patient revealed malignant PEComa without lymph node and omentum involvement. Conclusion: Diagnosis of PEComa before surgery is difficult and its differential diagnoses form uterine leiomyoma or leiomyosarcoma. Final diagnosis can be made after surgical biopsy and immunohistochemistry evaluation. Surgery is still the main treatment and adjuvant therapy is used in high risk patients.

Using Bakri balloon as a visceral replacement for occupying pelvic cavity in pelvic exenteration, a case report.

INTRODUCTION AND IMPORTANCE: Total pelvic exenteration is the choice treatment for locally advanced or recurrent cervical cancers. However, the procedure is usually associated with serious complications. One of the most common complications is "empty pelvic syndrome". In this case report, we described a novel method to investigate its efficacy in prevention of empty pelvic syndrome. CASE PRESENTATION: A 51-year-old woman presented with recurrent cervical cancer underwent TPE after chemoradiotherapy. After removing the organs of the pelvic cavity, a silicone-made Bakri balloon was placed in there through the laparotomy incision. The balloon was removed 5 days later through the vaginal canal. She was followed for 6 months after the surgery and did not experience neither complications nor the recurrence of the cervical cancer. CLINICAL DISCUSSION: We intended to use a novel technique by placing a Bakri balloon in the pelvic cavity after the total pelvic exenteration. The silicone-made balloon creates an appropriate physical barrier to support colon and small intestine loops and other pelvic contents. CONCLUSION: Bakri balloon, which has been used to control the post-partum hemorrhage, can be a useful tool to provide a physical barrier to prevent the descending of intestinal loops and a breeding ground for reconstruction of the pelvic floor.

Evaluation of the diagnostic accuracy of the cervical biopsy under colposcopic vision.

This study was conducted to evaluate the diagnostic accuracy of the cervical biopsy under colposcopic vision. This retrospective study was performed on 190 women, who were selected from a total of 412 cases referring for colposcopy in one year. All patients underwent colposcopy and loop electrosurgical excision procedure (LEEP). After the investigation of demographic characteristics and data confirmation, colposcopic characteristics were examined. Then, the diagnostic indicators and diagnostic accuracy of the cervical biopsy under colposcopic vision were determined. The mean age of patients was 35.51± 5.91 years. In smokers, the percentage of cancer and CIN3 cases was higher than in normal individuals, and this difference was statistically significant in terms of the frequency of cancerous lesions (P = 0.2). A comparison of colposcopic biopsy with LEEP has shown that the frequency of advanced cases in LEEP has been detected more, and the correlation coefficient (kappa) indicated the weak agreement between the findings of colposcopically directed biopsy (CDB) and LEEP methods. (k = 0.23). The diagnostic accuracy of the cervical biopsy under colposcopic vision for cervical cancer is effectively high. It is recommended that this procedure be performed to diagnose cancerous lesions; however, contrary to what is seen in colposcopy, malignant cases may be spreading and follow-up of patients can affect therapeutic performance.

Primary large B-cell lymphoma of the cervix: A case report and review of literature.

The primary diffuse large B-cell lymphoma (DLBCL) of the uterine cervix is extremely rare. In the present study, we described two cases of DLBCL of the uterine cervix in reproductive-aged women complaining of postcoital bleeding, recurrent vaginal discharge, and abnormal uterine bleeding.

Diagnostic accuracy for alternative cervical cancer screening strategies: A systematic review and meta-analysis.

We performed a systematic review and meta-analysis to evaluate the accuracy of screening cervical cancer tests as alternative standalone methods. The combined estimates of sensitivity of visual inspection with acetic acid, visual inspection with lugol's iodine, conventional pap smear, liquid-based cytology, High risk HPV testing by clinician, High risk HPV testing by self- sampling, cervicography were 64%, 80%, 55%, 70%, 70% and 67% respectively; the combine values of specificity of these screening strategies were 88%, 88%, 96%, 59%, 94%, and 95% respectively. Our findings draw attention to an attractive opinion to facilitate the collection of specimens for DNA HPV by patients in settings where they don't have access to a regular screening programs.

Spontaneous Intracerebral Hemorrhage (ICH) associated with pregnancy and SARS-CoV-2 infection: a case report.

BACKGROUND: Coronavirus Disease 2019 (COVID-19) is predominately known as a respiratory disease associated with pneumonia, acute respiratory distress syndrome and multiorgan failure. However, extra-pulmonary complications of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are increasingly being recognized. In this regard, some studies implied the hemostatic and vascular involvements in patients with SARS-CoV-2 infection. CASE PRESENTATION: We describe a case of spontaneous Intracerebral Hemorrhage (ICH) in a pregnant patient with COVID-19 and history of cesarean section a week before the occurrence of ICH. The patient underwent emergent craniotomy with acceptable outcome. Hemorrhagic events, including ICH, may happen during COVID-19 infection with several possible mechanisms. CONCLUSION: COVID-19 patients, especially high-risk groups, are at a risk of intracranial hemorrhage. Therefore, close follow-up must be maintained and hemorrhagic events must be kept in mind in these cases.

Efficacy of daily rectal micronized progesterone for prevention of preterm delivery: a randomized clinical trial.

INTRODUCTION: Preterm delivery is the leading cause of neonatal morbidity and mortality and its prevention is always under serious concern. OBJECTIVE: The aim of the present study was to determine the efficacy of rectal progesterone as a maintenance tocolytic after arresting preterm labor, for increasing the duration of pregnancy, and postponing preterm birth. METHOD: The study was performed as a double blind randomized clinical trial on women with preterm labor in whom contractions have been stopped. The eligible women were randomly divided into two groups. In the intervention group (progesterone group), progesterone was administered rectally as a dose of 200 mg daily until 36+6 weeks or spontaneous delivery before that time, whichever came first; and in the placebo group, placebo was administered in a similar manner. Primary outcomes were number of deliveries before 37 weeks of gestation and time to delivery interval in two groups. Secondary outcomes were neonatal Apgar score and weight, and need for NICU admission. RESULTS: 160 women finished the study (80 women in each group). The women of the two groups did not have significant difference according to the baseline characteristics. Frequency of preterm labor (earlier than 37 weeks) and mean gestational age at the time of delivery did not show significant difference in two groups. Also, neonatal outcome including Apgar score, birth weight, NICU admission and neonatal complications were not different between the two groups. The pregnancy length was longer in progesterone group (28.84 ± 3.36 VS 21.19 ± 4.62 days), [p = .001, CI 95%: 3.71-4.83]. The time-to-event (delivery) analysis showed a hazard ratio of 1.02 (95% CI 0.36-2.77). CONCLUSION: Rectal progesterone at a daily dose of 200 mg as a maintenance tocolytic agent, cannot lower the frequency of preterm delivery but was suggested to prolong pregnancy length.

Rhabdomyosarcoma of the uterus in an adult patient with osteopetrosis: a case report.

BACKGROUND: Uterine sarcoma accounts for 3-7% of uterine malignant neoplasms. It is more aggressive than epithelial neoplasms, and patients have a poor prognosis. Rhabdomyosarcoma is classified as a heterologous uterine sarcoma. It is the most common soft tissue malignancy in children while rare in adults. In young patients, the majority of genital tract rhabdomyosarcomas occur in vagina; however, the most common site of gynecologic rhabdomyosarcoma is cervix followed by uterine corpus, in adults. Uterine corpus rhabdomyosarcoma is rare in adults. Diagnosis of pure rhabdomyosarcoma in uterus involves widespread and perfect sampling as well as precise histopathological evaluation to uncover any epithelial component. CASE PRESENTATION: Here we report a case of pure rhabdomyosarcoma of uterine corpus in a 60-year-old Iranian postmenopausal female who had osteopetrosis, presenting with 8-month heavy vaginal bleeding and a protruding cervical mass. She is alive on 18-month follow-up after treatment. CONCLUSIONS: Rhabdomyosarcoma of uterine corpus is rare in adults. Diagnosis of pure rhabdomyosarcoma in uterus involves widespread and perfect sampling as well as precise histopathological evaluation to uncover any epithelial component. Treatment options in adult gynecological rhabdomyosarcoma are based on studies in younger patients, and more studies may help us choose the best approach for improving outcome.

Investigation of TGF-ß1 gene variant and expression in a group of Iranian women with endometriosis.

PURPOSE: Endometriosis is defined as a common gynecologic and inflammatory disease. Transforming growth factor-beta 1 (TGF-ß1) gene and its protein level might play a role in the pathogenesis of endometriosis. The present study aimed for the first time to assess the associations between endometriosis risk and - 509 C/T (rs1800469) variant of the TGF-ß1 gene as well as TGF-ß1 mRNA expression in eutopic endometrium tissue of patients with and without endometriosis among a group of Iranian women. METHODS: Genotyping was carried out in 100 endometriosis patients (cases) with confirmed histological diagnosis of endometriosis and 197 non-endometriosis subjects (controls). The expression level of TGF-ß1 mRNA was determined using Real-Time PCR assay in 15 eutopic endometrium tissue of women with endometriosis and 15 healthy controls. RESULTS: There was a significant association for allele and genotype frequencies of rs1800469 variant and endometriosis. No significant difference for TGF-ß1 expression was observed between eutopic endometrium of patients and healthy group. Also, evaluation of TGF-ß1expression across the menstrual cycle showed the same level of TGF-ß1 among case and control subjects. CONCLUSION: Our investigations indicated enough evidence for the effect of TGF-ß1 genetic variant on endometriosis risk in an Iranian population. Furthermore, we could not find any relations between TGF-ß1 mRNA expression and susceptibility to endometriosis.

Prevalence and Genotype Distribution of Human Papillomavirus Infection among 12 076 Iranian Women.

INTRODUCTION: Human papillomavirus (HPV) infection is one of the major health concerns of women in developing countries. This study gives an insight into the prevalence and genotype distribution of HPV infection and compares it with Pap smear results among Iranian women. METHODS: In this study, 12 076 Iranian women underwent routine examination from November 2016 to November 2018 using HPV Direct Flow CHIP System for HPV DNA typing. Cytology was undertaken for 5138 samples. RESULTS: Overall HPV prevalence was calculated at 38.68%. The most frequent HPV types were HPV 6, 16, 11, 62/81, 52 and 54. The most high-risk HPV (HR-HPV) types were HPV 16, 52, 18, 39, 31 and 51. These 2 groups represent approximately half of all HPV types detected, 47% and 55%, respectively. Among individuals who underwent cytological tests, 135 individuals (2.63%) were cytologically positive. In this group, 81 individuals (60%) were HPV positive, 62 (76%) of whom were HR-HPV positive, most frequently with HPV 16 (34%). CONCLUSION: This study highlights the urgent need for public education and early diagnosis using HPV screening tests to prevent cervical cancer.

Pulmonary embolism in pregnancy with COVID-19 infection: A case report.

Pregnant women in the third trimester are at the highest risk. Contracting COVID-19 increases the complications. Hence, it is critical for pregnant women, especially during the third trimester, with slightest COVID-19 symptoms to visit as soon as possible. Early diagnosis considerably contributes to saving both the mother and the fetus.

A COVID-19 pregnant patient with thrombotic thrombocytopenic purpura: a case report.

BACKGROUND: Pregnancy seems to increase the risk of thrombotic thrombocytopenic purpura (TTP) relapses and make the TTP more severe in any of the pregnancy trimesters, or even during the postpartum period. CASE PRESENTATION: This study highlights details of treating a COVID-19 pregnant patient who survived. This 21-year addicted White woman was admitted at her 29th week and delivered a stillbirth. She was transferred to another hospital after showing signs of TTP, which was caused by a viral infection. CONCLUSION: This viral infection caused fever and dyspnea, and the patient was tested positive for COVID-19 infection. A chest computed tomography scan showed diffuse multiple bilateral consolidations and interlobar septal thickening. She stayed at the Intensive Care Unit for 20 days and treated with plasmapheresis. As far as we know, this is the first report of a TTP pregnant patient with COVID-19 infection.

Investigating the association of matrix metalloproteinase-2 gene variants with endometriosis in an Iranian population.

OBJECTIVES: matrix metalloproteinases including matrix metalloproteinase-2 play a key role in endometrial extra cellular matrix breakdown in endometriosis. Aberrant expression of matrix metalloproteinase-2 has been reported in eutopic and ectopic endometrial tissue of endometriosis patients so altered expression of matrix metalloproteinase-2 due to polymorphisms may lead to establishment and progression of endometriosis. In this study the association between -735 C/T (rs2285053) and -1575 G/A (rs243866) variants of matrix metalloproteinase-2 gene with presence of endometriosis in an Iranian population were investigated for the first time. STUDY DESIGN: A case-control association study was conducted to investigate the role of MMP-2-735 C/T and _1575 G/A variants in development of endometriosis. Polymerase chain reaction-restriction fragment length polymorphism method was used to determine genotype frequencies of these variants in 100 endometriosis patients and 200 normal samples. Total genomic DNA was extracted from blood samples and single-nucleotide polymorphism flanking regions were amplified using designed specific primers. Enzymatic digestion was performed using Pag I and Hinf I restriction enzymes for rs2285053 and rs243866 variants, respectively. Statistical analysis was ascertained using statistical package for social science version 16 and "SHEsis" software. RESULTS: There were no significant differences in genotype frequencies of rs2285035 (-735C/T) variant between case and control groups (CC + CT vs. TT p = 0.40; OR = 0.50, 95 % CI 0.100-2.551). There were also no significant differences for C allele frequencies in both case and control groups (p = 0.9). For variant rs243866 (-1575 G/A) the differences in genotype frequencies between case and controls group were determined to be significant (GG + GA vs. AA p = 0.041; OR = 6.46, 95 % CI 0.82-50.43). The frequency of G allele was significantly different in case and control groups (p = 0.037). CONCLUSION: In conclusion, existence of rs243866 variant in promoter region of matrix metalloproteinase-2 gene can increase the risk of endometriosis in Iranian women.

A Case of COVID-19 Mortality in a Pregnant Woman with Diabetes Ketoacidosis.

SARS-CoV-2 is a newly identified virus that causes COVID 19, spreading very fast in the world. Uncontrolled diabetes in pregnancy can increase the risk of pregnancy outcomes. Pregnant women are at high risk of developing a viral infection, like SARS-COV and on the other hand, diabetes ketoacidosis (DKA) which is coupled with COVID-19, can increase maternal mortality. The patient was a 27-years-old female G3P1L1Ab1 with a history of a previous cesarean section. On 26 March 2020, a fetal ultrasound revealed intra-uterine fetal death (IUFD) and also diagnosis of DKA and COVID-19 in the patient that she was expired eventually due to the uncontrolled DKA. In this case report, a pregnant woman with a diagnosis of IUFD, DKA and COVID-19 simultaneously is described. To the best of the authors of this paper's knowledge, no previous work has been reported for the comorbidity of diabetes and COVID-19 in pregnancy, but it seems that the coincidence of the above-mentioned diseases can delay the recovery period and also can increases maternal and fetal mortality. When DKA and COVID-19 appear in the patient simultaneously, we cannot control DKA by the routine protocol treatments of DKA which were used formerly.
