Adult type granulosa cell tumor of the testis: case report and review of the literature.

Testicular granulosa cell tumors are extremely rare in adults. We report a case of a testicular germ cell tumor (GCT) in a 21-year-old man. The tumor was treated successfully with radical orchiectomy, and follow-up computed tomography revealed no evidence of recurrence or metastasis 10 months postoperatively. The clinical and histopathological features, treatment, and prognosis of testicular GCT are reviewed in this manuscript.
