傍睾丸横紋筋肉腫の1例

Abstract

A 22-year-old student was admitted to our hospital because of the chief complaint of painless mass of the right scrotal content on August 26, 1977. There was neither history of antecedent trauma nor fever. A thumb-head-sized, hard, rough surfaced and no tender mass was palpated on the spermatic cord near the head of right epididymis. The right testis and epididymis were almost normal. A bone and chest X-ray, excretory urogram and laboratory findings were normal. On August 31, radical orchiectomy was performed. The tumor was 3.0×4.7×2.0 cm in size and 12 gm in weight. The tumor was able to be isolated from both testis and epididymis, and then it seemed to have arisen from the right testicular tunics. The histopathological diagnosis was made as mixed type of pleomorphic and embryonal rhabdomyosarcoma. The patient received chemotherapy with Endoxan but no radiation therapy. He is living without metastasis during four months after the operation. Including our case, 54 cases of the paratesticular rhabdomyosarcoma have been reported in the Japanese literatures. The diagnostic, therapeutic and prognostic problems were discussed in this paper.
