BACKGROUND
Mature cystic teratomas (MCT) of the ovary are benign ovarian germ cell neoplasms. Malignant transformation is possible but rare and ovarian carcinoid tumors in MCT are among the most extremely rare subtypes.
CASE PRESENTATION
We report a case of a 60-year-old Iranian woman suffering from postmenopausal bleeding and hypogastric pain for the last 40 days. An adnexal mass was detected during the physical examination. Ultrasound imaging showed a (55 × 58) mm mass in the left ovary. Total abdominal hysterectomy, bilateral salpingooophorectomy and comprehensive staging surgery were performed for the patient. Intraoperative frozen section of the left ovarian mass was indicative of a malignant tumor. She was diagnosed with a carcinoid tumor with benign mucinous cystadenoma arising on MCT of the ovary, confirmed in the histopathology and immunohistochemistry examination. The tumor was classified as low grade and no chemotherapy cycles were considered. The patient was followed up long-term and no recurrence was observed during 14 months of examinations.
CONCLUSION
Ovarian carcinoids arising from MCT are rare neuroendocrine neoplasms, and proper diagnosis of these tumors requires careful histopathology evaluation and appropriate examination. Therefore, it is necessary to consider these tumors as a possible differential diagnosis and evaluate them in individuals (especially postmenopausal women) who have abdominal pain or abnormal bleeding and a palpable mass.

INTRODUCTION
Over the last decade there has been a transition from traditional laparoscopy to robotic surgery for the treatment of endometrial cancer. A number of gynecological oncology surgical fellowship programmes have adopted robot-assisted laparoscopy, but the effect of training on complications and survival has not been evaluated. Our aim was to assess the impact of a proficiency-based progression training curriculum in robot-assisted laparoscopy on peri-operative and survival outcomes for endometrial cancer.
METHODS
This is an observational cohort study performed in a tertiary referral and subspecialty training center. Women with primary endometrial cancer treated with robot-assisted laparoscopic surgery between 2015 and 2022 were included. Surgery would normally include a hysterectomy and salpingo-oophorectomy with some form of pelvic lymph node dissection (sentinel lymph nodes or lymphadenectomy). Training was provided according to a training curriculum which involves step-wise progression of the trainee based on proficiency to perform a certain surgical technique. Training cases were identified pre-operatively by consultant surgeons based on clinical factors. Case complexity matched the experience of the trainee. Main outcome measures were intra- and post-operative complications, blood transfusions, readmissions < 30 days, return to theater rates and 5-year disease-free and disease-specific survival for training versus non-training cases. Mann-Witney U, Pearson's chi-squared, multivariable regression, Kaplan-Meier and Cox proportional hazard analyses were performed to assess the effect of proficiency-based progression training on peri-operative and survival outcomes.
RESULTS
Training cases had a lower BMI than non-training cases (30 versus 32 kg/m, = 0.013), but were comparable in age, performance status and comorbidities. Training had no influence on intra- and post-operative complications, blood transfusions, readmissions < 30 days, return to theater rates and median 5-year disease-free and disease-specific survival. Operating time was longer in training cases (161 versus 137 min, = < 0.001). The range of estimated blood loss was smaller in training cases. Conversion rates, critical care unit-admissions and lymphoedema rates were comparable.
DISCUSSION
Proficiency-based progression training can be used safely to teach robot-assisted laparoscopic surgery for women with endometrial cancer. Prospective trails are needed to further investigate the influence of distinct parts of robot-assisted laparoscopic surgery performed by a trainee on endometrial cancer outcomes.

OBJECTIVES
To assess the association of socioeconomic demographics with recommendation for and uptake of risk-reducing bilateral salpingo-oophorectomy (rrBSO) in patients with and () mutations.
DESIGN
Retrospective cohort, semistructured qualitative interviews.
SETTING AND PARTICIPANTS
2 mutation carriers at an urban, public hospital with a racially and socioeconomically diverse population.
INTERVENTION
None.
PRIMARY AND SECONDARY OUTCOMES
The primary outcomes were rate of rrBSO recommendation and completion. Secondary outcomes were sociodemographic variables associated with rrBSO completion.
RESULTS
The cohort included 167 patients with mutations of whom 39% identified as black (n=65), 35% white (n=59) and 19% Hispanic (n=32). Over 95% (n=159) received the recommendation for age-appropriate rrBSO, and 52% (n=87) underwent rrBSO. Women who completed rrBSO were older in univariable analysis (p=0.05), but not in multivariable analysis. Completion of rrBSO was associated with residence in zip codes with lower unemployment and documented recommendation for rrBSO (p<0.05). All subjects who still received care in the health system (n=79) were invited to complete interviews regarding rrBSO decision-making, but only four completed surveys for a response rate of 5.1%. Themes that emerged included menopause, emotional impact and familial support.
CONCLUSIONS
In this understudied population, genetic counselling and surrogates of financial health were associated with rrBSO uptake, highlighting genetics referrals and addressing social determinants of health as opportunities to improve cancer prevention and reduce health inequities. Our study demonstrates a need for more culturally centred recruiting methods for qualitative research in marginalised communities to ensure adequate representation in the literature regarding rrBSO.

Giant mucinous cystadenocarcinoma of the ovary is rarely described. Huge ovarian masses are mostly benign, but malignancy should be ruled out by investigations and clinical assessment. Here, we present a case of a large mucinous cystadenocarcinoma of the ovary in a 48-year-old postmenopausal woman. Imaging examinations revealed a large cystic tumor that filled the whole abdominal cavity. Despite the difficulties presented by the size of the tumor and its malignant potential, laparotomy was carried out, which included bilateral salpingo-oophorectomy, total abdominal hysterectomy, exploration of other intra-abdominal organs, and pelvic lymphadenectomy. Histopathology indicated the presence of mucinous cystadenocarcinomas. Adjuvant chemotherapy was given post-operatively, and the patient maintained remission during follow-up. This case emphasizes the need for early detection by simple imaging modalities such as ultrasonography in cases of ovarian masses. Most adnexal masses, if detected early, are amenable to surgical management with a good prognosis. Large masses underline the need for a multidisciplinary approach to improve patient outcomes.

BACKGROUND
Endometrial adenosarcoma is an unusual type of uterine tumor that features a seemingly benign epithelial component, paired with a low-grade sarcomatous component, usually similar in appearance to endometrial stromal sarcoma. To our knowledge, no image of endometrial adenocarcinoma in the cesarean scar diverticulum has been reported previously.
CASE DESCRIPTION
We present a rare case of endometrial adenocarcinoma located in the cesarean scar diverticulum of a 44-year-old patient. The patient was admitted to our hospital complaining of irregular vaginal bleeding that had lasted for over two months. Both B-ultrasound and magnetic resonance imaging confirmed a mass at the junction of the corpus uteri and cervix. After the initial curettage failed to confirm the disease, a hysteroscopy was subsequently performed. Upon further pathological analysis, a diagnosis of endometrial adenosarcoma was confirmed. The patient underwent hysterectomy and salpingo-oophorectomy. The patient was discharged home four days after the surgery and remained recurrence-free for one year after follow-up.
CONCLUSIONS
Hysteroscopy can serve as a valuable diagnostic tool to identify the lesion in this unique scenario, particularly when curettage fails to diagnose this uncommon condition. We hope that this case would bring awareness of this potential scenario, enabling clinicians in the future to identify similar cases more readily.

Occult clear cell carcinoma arising from oxidative stress‑exposed cystic adenomyosis: A case report.Molecular and Clinical Oncology Jul 2024Although adenomyosis is a benign uterine disease, it can turn malignant in rare instances.

Although adenomyosis is a benign uterine disease, it can turn malignant in rare instances. Cystic adenomyosis is a rare variation of adenomyosis, arising from which 8 cases of clear cell carcinoma have been reported. However, to the best of our knowledge, there have been no previous reports describing the mechanism by which clear cell carcinoma develops from cystic adenomyosis. The present report documents a case of a 73-year-old woman who was referred to Kanazawa University Hospital (Kanazawa, Japan) because of cystic adenomyosis, with a solid part inside the cyst. The patient was diagnosed with cystic adenomyosis at Shonan Obstetrics and Gynecology Hospital (Hakusan, Japan) 17 years prior; however, the size of the cyst increased after menopause. Therefore, malignant transformation was suspected, which warranted simple abdominal hysterectomy and bilateral salpingo-oophorectomy. The final diagnosis of the present case was uterine corpus cancer, clear cell carcinoma, stage IA. Immunohistochemical staining revealed that the normal and transitional atypical epithelial cells lining the cyst wall, in addition to the clear cell carcinoma cells (which were inside mural nodules located on the cyst wall), were positive for 8-hydroxy-20-deoxyguanosine. This observation suggested the presence of chronic oxidative stress around the cystic adenomyosis. Therefore, the present case suggests the possible involvement of chronic oxidative stress in the malignant transformation of cystic adenomyosis to clear cell carcinoma. This mechanism of malignant transformation of cystic adenomyosis appears to be similar to that of the malignant transformation of endometriotic cysts. Therefore, if the size of the cystic adenomyosis increases after menopause or if the solid part appears in the cyst in future cases, then the possibility of malignant transformation should be considered.

We report an asymptomatic 59-year-old female undergoing an elective umbilical hernia excision who was found to have an ovarian adenocarcinoma within the excised hernia. Patients are rarely diagnosed with cancer after an umbilical hernia excision. An excised hernia is rarely the means for an initial diagnosis of cancer. We describe a case of an ovarian carcinoma incidentally found through an umbilical hernia excision with consequential treatment with neoadjuvant platinum-based chemotherapy followed by debulking surgery with a total hysterectomy with bilateral salpingo-oophorectomy with a transoperative pathology report of a high-grade serous carcinoma located in the left fimbrial frond surrounded by a background of serous tubal intraepithelial carcinomas. This case demonstrates the need to perform histological examinations of all excised hernias, even in asymptomatic patients, as malignancy can be found inside a hernia, and it emphasizes the importance of considering adenocarcinomas of Mullerian origin in the differential diagnosis of a malignancy found in a hernia in an asymptomatic female patient.

Comprehensive next-generation sequencing identifies novel putative pathogenic or likely pathogenic germline variants in patients with concurrent tubo-ovarian and endometrial serous and endometrioid carcinomas or precursors.
BACKGROUND
Endometrial serous carcinoma (ESC) and tubo-ovarian high-grade serous carcinoma (HGSC) are characterized by late-stage presentation and high mortality. Current guidelines for prevention recommend risk-reducing salpingo-oophorectomy (RRSO) in patients with hereditary mutations in cancer susceptibility genes. However, HGSC displays extensive genetic heterogeneity with alterations in 168 genes identified in TCGA study, but current germline testing panels are often limited to the handful of recurrently mutated genes, leaving families with rare hereditary gene mutations potentially at-risk.
OBJECTIVE
To determine if there are rare germline mutations that may aid in early identification of more patients at-risk for ESC and/or HGSC by evaluating patients with concurrent ESC, HGSC or precursor lesions, and endometrial atypical hyperplasia (CAH) or low-grade endometrial endometrioid adenocarcinoma (LGEEA).
METHODS
We performed targeted next-generation sequencing using TSO 500, a 523 gene panel, on formalin-fixed paraffin-embedded tumor and matched benign non-tumor tissue blocks from 5 patients with concurrent ESC, HGSC or precursor lesions, and CAH or LGEEA.
RESULTS
We identified germline pathogenic, likely pathogenic or uncertain significance variants in cancer susceptibility genes in 4 of 5 patients - affected genes included GLI1, PIK3R1, FOXP1, FANCD2, INPP4B and H3F3C. Notably, none of these genes were included in the commercially available germline testing panels initially used to evaluate the patients at the time of their diagnoses.
CONCLUSION
Comprehensive germline testing of patients with concurrent LGEEA or CAH and ESC, HGSC or precursor lesions may aid in early identification of relatives at-risk for cancer who may be candidates for RRSO with hysterectomy.

Significant progress has been made in the molecular diagnosis of cancer. It provides personalized medicine, including cancer diagnosis, prognosis, targeted therapy, and risk detection. These advances allow physicians to identify patients at risk for cancer before it develops and offer them an opportunity to prevent its development. Mutations in breast cancer susceptibility genes 1 and 2 (BRCA1 and 2) are one of the most well-known cancer-related gene mutations since actor Angelina Jolie shared her experience with genetic mutations and risk-reducing surgery in the media. In Korea, tests for germline BRCA1/2 mutations have been covered by insurance since May 2012 and the number of carriers of BRCA1/2 mutations has continued to increase over the past decade. Most carriers of BRCA1/2 mutations consider risk-reducing salpingo-oophorectomy (RRSO) resulting in early menopause and want to know the lifetime risks and benefits of RRSO. However, despite the increasing number of carriers of BRCA1/2 mutations, the counseling and management of patients requiring RRSO varies among physicians. This article provides basic knowledge on RRSO to help physicians comprehensively assess its risks and benefits and manage at-risk women.

BACKGROUND Malignant peritoneal mesothelioma is a rare disease with a poor prognosis that often presents with vague symptoms and inconclusive laboratory test results. Causes include industrial pollutants, primarily asbestos, and certain genetic mutations, such as BAP1. Due to the nonspecific symptoms, it is often incidentally diagnosed during or after other surgical procedures. CASE REPORT A 35-year-old healthy woman underwent an uncomplicated laparoscopic left salpingo-oophorectomy for a symptomatic large ovarian mature cystic teratoma. She subsequently presented with late-onset postoperative fever, leukocytosis, and multiple intra-abdominal masses. Following an exploratory laparotomy, extensive infectious disease evaluation, and multiple biopsies requiring interdisciplinary collaboration, malignant peritoneal mesothelioma was diagnosed by positive histologic staining of an omental biopsy for D2-40 and CK5/6. This first specimen was positive for BAP1, with the second, a liver biopsy, testing negative for BAP1. The tumor cell testing was also notable for mutations in NF2, MLL2, and ARID1A, and the hereditary cancer genetic testing was overall unremarkable. Her disease progressed rapidly, and she died 6 months after her initial procedure. CONCLUSIONS This case of rapidly developing malignant peritoneal mesothelioma following surgical management of an ovarian mature teratoma highlights the complexity in diagnosing a rare disease that presents with nonspecific symptoms in an otherwise young and healthy woman. The rapid disease course was likely accelerated by expansive intraperitoneal spread and multiple somatic oncogenic mutations in BAP1, NF2, MLL2, and ARID1A. Gynecologists should keep a broad differential for postoperative complications, as occult malignancies can present with symptoms that mimic postoperative complications.
