Low-grade endometrioid adenocarcinomas presenting as stage III carcinoma

Endometrioid adenocarcinomas are the most common form of endometrial adenocarcinoma in postmenopausal women. It is stressed that histological grade corresponds to the stage of the tumor and has an impact on the prognosis and survival of the patient. We present a case of 45-year-old female patient who presented with grade 1 endometrioid adenocarcinoma involving bilateral ovaries and peritoneal washings, corresponding to stage IIIa tumor. She also showed the synchronous presence of serous cystadenoma of the right ovary. We report this case as it is an advanced stage endometrioid adenocarcinoma with lower histological grade and also due to the synchronous presence of right ovarian serous cystadenoma.
