[A case of bilateral testicular germ cell tumor]

A case of bilateral successive tumor of germ cell origin is reported. A 29-year-old man visited our clinic with a complaint of swelling of right scrotal contents 18 months after initial left orchiectomy for a seminoma. The right orchiectomy was performed and its histological finding was also seminoma. Between 1965-1987 we treated 55 patients with testicular germ cell tumors. Two of them suffered a second germ cell tumor. One of them who had different histology of teratocarcinoma on left side and seminoma on right side had been reported previously. Herein, we report the second case and review the literature.
