Proliferative Brenner tumor of the ovary.
A 72-year-old woman was admitted with abdominal distention and a hard mass in the pelvis. Abdominal laparotomy was performed, and a large solid left ovarian tumor was found. Left salpingo-oophorectomy was carried out. Histology showed cords and nests of stratified high cellular epithelium with dense eosinophilic material in epithelial nests and dense fibrous stroma identified as a Brenner tumor of the ovary. Because mild to moderate cytologic atypia with mitotic activity was present, a diagnosis of proliferative Brenner tumor was made. After the operation, the patient was in good condition with no recurrence or metastasis so far.
