Synchronous benign Brenner's tumor of ovary with leiomyoma and endometrial adenocarcinoma in a postmenopausal female.

Brenner tumors of ovary are usually an incidental finding. It is an uncommon tumor which is seen affecting women of fifth to sixth decade. It is classified under transitional cell tumors of ovary, which includes benign, borderline, and malignant Brenner tumors and transitional cell carcinoma. These tumors have been associated with synchronous and metachronous neoplasia, most commonly other ovarian epithelial tumors such as mucinous cystadenoma. Occasionally, these tumors may be associated with endometrial hyperplasia or carcinomas which are due to hormones elaborated by the stromal component of Brenner tumor. The hormone produced is estrogen and less commonly androgens, which alters the estrogen and progesterone levels, causing hyperstimulation of endometrium. We present a case of 50-year-old postmenopausal women who presented with coexisting incidental Brenner tumor with leiomyoma and Endometrial adenocarcinoma. Only few authors have reported similar tumor occurrence in the past.
