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…

Primary endometrioid adenocarcinoma rarely occurs in the vagina. Occasionally, endometrioid adenocarcinoma has a microglandular pattern. Herein, a case of primary endometrioid adenocarcinoma of the vagina with a microglandular pattern arisi…

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 …
