Borderline clear cell adenofibroma with extensive hemorrhagic necrosis

ABSTRACT

Borderline clear cell adenofibroma of the ovary is rather rare since most of clear cell tumors are carcinomas. We report a case of ovarian borderline clear cell adenofibroma in a 52-year-old postmenopausal woman. The tumor had the characteristic histologic features of borderline clear cell adenofibroma except for central extensive hemorrhagic necrosis. The prognosis of borderline clear cell adenofibroma is excellent. Because the invasiveness cannot be assessed in the necrotic areas, our patient needed long-term follow-up
