A case of bilateral testicular germ cell tumors in a 23-year-old male is reported. He was admitted to the Department of Urology, Yamagata Prefecture Kahoku Hospital with the chief complaint of painless swelling in the left intrascrotal contents. Left high inguinal orchiectomy was carried out. At the same time, right hydrocele operation and right testicular biopsy were performed.

On July 21, 1988, he was referred to our clinic and right high inguinal orchiectomy was carried out. Postoperative chemotherapy was performed with CDDP, VP-16 and peplomycin, and postoperative course was uneventful with no distant metastasis or local recurrence.
