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.

Postoperative chemotherapy was performed with CDDP, VP-16 and peplomycin, and postoperative course was uneventful with no distant metastasis or local recurrence.
