We report a rare case of infantile synchronous bilateral testicular teratoma treated by testis sparing surgery. Preoperative ultrasonography, tumor marker status and intraoperative findings were suggestive of benign neoplasia. Under these circumstances we performed high orchiectomy for the left testis and testis sparing surgery for the right. Surgical treatment of teratoma in childhood is controversial, especially when it occurs bilaterally. In this report we discuss testis sparing surgery as the treatment for this disease.
