A 57-year-old white male presented with a 5-month history of a painless right testicular mass. Physical examination revealed a right testicular tumor. The patient underwent a right inguinal orchiectomy. Histopathologic evaluation showed a primary spindle-cell sarcoma of the testis. A retroperitoneal lymph node dissection was performed and revealed no lymphatic metastases. There was no recurrence of the disease over a 2-year follow-up period.
