Gynandroblastoma With Juvenile Granulosa Cell Tumor and Concurrent Renal Cell Carcinoma

Gynandroblastoma is an extremely rare primary tumor of the ovary showing morphological evidence of both female (granulosa cell tumor) and male (Sertoli or Sertoli–Leydig tumor) differentiation. We report an unusual case of a 32-year-old female who presented with hyperandrogenism and was found on imaging to have concurrent ovarian and renal masses. Following surgical excision, the ovarian mass was diagnosed as gynandroblastoma, which consisted of 45% juvenile granulosa cell tumor and 55% intermediately differentiated Sertoli–Leydig tumor. The renal mass was diagnosed as a conventional renal clear cell carcinoma. Gynandroblastoma, especially with juvenile granulosa cell tumor, is an extremely rare ovarian tumor. Concurrent gynandroblastoma with another malignant neoplasm has not been reported in the literature.
