title: Malignant sex cord-stromal tumor of testis.
abstract: We report a case of sex cord-stromal tumor in the testis, which metastasized to the retroperitoneal space, resulting in death 13 months after orchiectomy. The primary lesion consisted of granulosa cells, theca cells, Sertoli cells and undifferentiated gonadal stroma. Biopsy of the retroperitoneal metastasis showed predominance of the Sertoli cell component.
