Obturator nerve injury is a rare complication of pelvic lymphadenectomy in gynecologic oncology. We report a case of intraoperative obturator nerve transection and its successful laparoscopic repair. A 73-year-old woman with stage IB1 cervi…

PurposeTo investigate the influence of microcystic, elongated and fragmented (MELF) pattern invasion on preoperative evaluation of lymph node (LN) metastasis and myometrial invasion in patients with low-grade endometrial carcinoma.MethodsTh…

Ovarian clear cell carcinoma (CCC) exhibits an association with endometriosis, resistance to oxidative stress, and poor prognosis owing to its resistance to conventional platinum-based chemotherapy. A greater understanding of the molecular …

Low-grade endometrial stromal sarcoma (LG-ESS) is a rare malignant disease and demonstrates various patterns in preoperative imaging. Therefore, accurate diagnosis is important. Given its unique form, we report a case of LG-ESS with a nodul…

BackgroundVulvar cancer and vaginal cancer are relatively rare tumors, and there had been no established treatment principles or guidelines to treat these rare tumors in Japan. The first version of the Japan Society of Gynecologic Oncology …

Endometrioid borderline tumours (EBTs) of the ovary are uncommon tumours of low malignant potential. They consist of atypical endometrioid cells lacking destructive stromal invasion. As the prognosis of EBT is excellent, excessive treatment…

Somatic mutations in the ARID1A tumor-suppressor gene have been frequently identified in ovarian clear cell carcinoma (CCC) cases. BAF250a encoded by ARID1A is a member of the SWI/SNF complex, but the expression and mutation status of other…

Ovarian clear cell carcinoma (OCCC) is a morphologically and biologically distinct subtype of ovarian carcinomas that often arises in ovarian endometriosis. We previously reported that a unique carcinogenic environment, especially iron-indu…

A uterus-like mass is an extrauterine mass with a cavity lined by endometrial tissue and a smooth muscle layer resembling the uterine corpus. It is a rare condition of unknown histogenesis. Herein, we describe a case of clear cell carcinoma…

Ovarian clear cell carcinoma has unique clinical characteristics with slow growth and a stress-resistant phenotype that is epigenetically induced during cancer progression in an inflammatory microenvironment. We refer to this as an epigenet…

Targeted approaches have revealed frequent epigenetic alterations in ovarian cancer, but the scope and relation of these changes to histologic subtype of disease is unclear. Genome-wide methylation and expression data for 14 clear cell carc…

In an attempt to clarify the clinical characteristics of synchronous primary endometrial and ovarian cancer (SPC), we reviewed the clinicopathological features of 13 cases treated in the Department of Gynecology and Obstetrics at Kyoto Univ…

Although it is well known that ovarian endometriosis occasionally gives rise to ovarian cancers with specific histology such as endometrioid and clear cell carcinomas, its etiology is not fully understood. We have shown that a stressful mic…

Ovarian clear cell carcinoma (OCCC) shows unique clinical features including an association with endometriosis and poor prognosis. We previously reported that the contents of endometriotic cysts, especially high concentrations of free iron,…

Primary mucinous adenocarcinomas of the uterine corpus are typically low grade and frequently associated with endometrial hyperplasia and/or ordinary endometrioid adenocarcinoma, but may appear as a heterogeneous group of neoplasms. A case …

Recent molecular and pathological evidence suggests that endometriosis is a monoclonal, neoplastic disease. Moreover, endometriosis serves as a precursor of ovarian cancer (endometriosis-associated ovarian cancer; EAOC), especially of the e…
