[A case of embryonal rhabdomyosarcoma of the spermatic cord].

A case of rhabdomyosarcoma of the spermatic cord in a 6-year-old boy is reported. On February 26, 1986, he visited Nakamura Hospital with the chief complaint of enlargement of the left scrotal content. The contralateral scrotum was normal. The left scrotal content was a hard thumb-head-sized tumor. The left testis and epididymis were not distinguishable from the tumor. On the same day, left high inguinal orchiectomy was performed. The tumor was 3.5 by 2.5 by 2.5 cm in size and was distinguishable from the testis, epididymis and tunica vaginalis. Histopathological findings were embryonal rhabdomyosarcoma and it appeared to have originated from the spermatic cord. Two years after operation, the boy is living without metastasis. Including our experience, 101 cases of the paratesticular rhabdomyosarcoma found in Japanese literature are reviewed and briefly discussed.
