Abstract

Leysig cell tumor of testis arises from interstitial cells of the testis and is relatively rare, comprising only 1.4 to 3 percent of all testicular tumors. This neoplasm can occur at any age. When it occurs in children, it is frequently accompanied by precocious puberty. But in adult patients, painless enlargement of the testis or a mass is the most common symptom and 25 percent of cases show gynecomastia. We report a case of Leydig cell tumor with typical gross and histological findings with review of literatures.
