[A case report: simultaneous bilateral testicular tumors with different cell types--complete response after combination chemotherapy of cisplatin and irrinotecan hydrochloride--].

A 38-year-old man was admitted to our hospital complaining of bilateral scrotal swelling. On examination, the patient was found to have bilateral testicular tumors with jugular chain lymph node and para-aortic lymph node metastasis. He underwent bilateral inguinal orchiectomy. Histopathological examination of the excised tumors revealed seminoma, embryonal carcinoma, yolk sac tumor and immature teratoma in the right testis and seminoma in the left testis. The patient was treated postoperatively with two courses of BEP (bleomycin, etoposide, cisplatin) therapy and two courses of EP (etoposide, cisplatinum) therapy. The patient had lung metastasis during the follow-up period and we treated him with salvage combination chemotherapy of cisplatin and irinotecan hydrochloride (CPT-11). After the third course of cisplatin and CPT-11 chemotherapy the lung metastasis disappeared and we performed retroperitoneal lymph node dissection. The patient has remained free of disease 11 months after discharge.
