Endometroid adenocarcinoma of the uterus, borderline tumor of the ovary and Brenner tumor of the contralateral ovary in a 63-year-old woman.

Synchronous primary cancers of the endometrium and ovary occur in approximately 10% of all women with ovarian cancer and 5% of all women with endometrial cancer. The pathogenesis of synchronous endometrial and ovarian cancer is unclear. Synchronous tumors tend to be low grade and early stage. The prognosis is much better with survival approaching ten years than if the disease was classified as a single organ disease with metastasis. We report a case of unusual co-existence of endometroid adenocarcinoma of the uterus, serous borderline tumor of the ovary and Brenner tumor of the contralateral ovary in a 63-year-old woman. The patient recieved a surgical treatment and postoperative irradiation.
