We carried out only high orchiectomy for a 1-year and 7-month-old boy with stage 1 yolk sac tumor of the testis, after 13-months a bulky retroperitoneal metastatic tumor was found. Following chemotherapy with CDDP, ACD, VBL, PLM and CTX two times after tumor resection, elevated serum AFP was normalized. He has been in continuous complete remission with no evidence of disease for 3 years and 2 months. Combination chemotherapy with CDDP has a dramatic effect on the yolk sac tumor of infantile testis. We believe that "watchful waiting" after high orchiectomy alone is the best modality for all cases of stage 1 yolk sac tumor of the infantile testis.
