[A case of cavernous hemangioma of the testis]

A 4-month-old boy was admitted with the chief complaint of painless mass in the right scrotum. A right testicular tumor complicated with hydrocele was diagnosed preoperatively by physical examination and ultrasonography. Right high orchiectomy was performed and the pathological diagnosis was cavernous hemangioma of the right testis. This disease is very rare, and our case is the 13th in the domestic and foreign literature.
