陰嚢内睾丸外横紋筋肉腫の1例

Abstract

A 7-year-old boy was admitted to Osaka University Hospital on March 13, 1967, with chief complaint of progressive enlargement of the right testicle. There was no history of antecedent trauma and no fever. The general examination was essentially negative. The left side of scrotum was normal. On the right side there was a hard, irregular, and non-tender mass. Differentiation of the testicle and the epididymis from the mass was not possible by palpation. The spermatic cord above the mass was normal Diagnostic study including excretory urogram and chest X-ray revealed normal On March 15, 1967, high orchiectomy was performed. The tumor was isolated from the testicle and the epididymis, and appeared to be originating from the tunica vaginalis. Histopathological diagnosis was rhabdomyosarcoma. Postoperative course was uneventful He was started on chemotherapy (Methotrexate) on the 10th day after operation. Nine months after operation, there was an evidence of metastases to retroperitoneal lymphnodes. Radiation therapy to the metastatic site was very effective. Seventy cases of the intrascrotal extratesticular rhabdomyosarcoma in the world literature were reviewed and discussed.
