Atypical Proliferating Clear Cell Adenofibroma of the Ovary: A Case Report

Clear cell adenofibromas of borderline malignancy are extremely rare tumors of the ovaries. They may be associated with ovarian clear cell adenocarcinomas which typically present as large adnexal masses and are generally considered highly malignant. We describe the case of a postmenopausal female with an ovarian mass diagnosed as atypical (borderline) proliferating clear cell adenofibroma. The patient is alive and well without signs of recurrence three years after surgery.
