[Simultaneous bilateral testicular tumors: a case report]

We report a case of bilateral simultaneously-occurring testicular tumors. A 43-year-old man was admitted to our clinic with a complaint of right inguinal pain in May 1992. Under the diagnosis of bilateral testicular neoplasms, bilateral high orchiectomy was performed. Histological examination revealed typical seminoma of bilateral testes. The patient was diagnosed with stage IIIO seminoma, and he was treated with combination chemotherapy (PVB). No evidence of disease has been seen after chemotherapy.
