[An operative case of spermatic cord rhabdomyosarcoma--with a review of similar cases in Japan].

A 17-year-old Japanese boy was admitted with the complaint of painless, progressive enlargement of the left scrotal contents during the preceding two months. The tumor was firm and nontender without transillumination. Orchitectomy with high ligatation of the spermatic cord was performed. The tumor, weighing 13.1 g, was gray, solid, located at the distal part of the spermatic cord, and separated from the testis and epididymis. The pathological diagnosis showed left spermatic cord rhabdomyosarcoma of the combined embryonal and alveolar type. All of the retroperitoneal lymph nodes dissected were negative for metastasis. The patient was treated with actinomycin D and vincristin postoperatively, and is well three years after the operation. Ninety-two cases of intrascrotal rhabdomyosarcoma reported in Japan are reviewed.
