Ovarian borderline clear cell adenofibroma in a 42-year-old woman: a case report and a literature review

Borderline clear cell adenofibroma of the ovary is rather rare since most clear cell tumors are carcinomas. Most patients with ovarian borderline clear cell adenofibroma are older than 50, with only a few cases of women younger than 50. Here, the authors report a 42-year-old woman with ovarian borderline clear cell adenofibroma. The surgical specimen was used for a pathological examination and immunohistochemistry. Macroscopically, the mass in the right ovary was relatively large, measuring 12×10×8 cm. Microscopically, the tumor showed the characteristic histologic features of borderline clear cell adenofibroma such as variation in size and shape of glands, cell atypia, and absence of stromal invasion. The patient had an uneventful recovery from the operation without any complications, recurrence, or metastasis during the two-year follow-up period. The prognosis of borderline clear cell adenofibroma is excellent, but the patient required long-term follow-up.
