[Rhabdomyosarcoma of the epididymis].
A 5-year-old boy with intrascrotal rhabdomyosarcoma arising from the epididymis is described. The patient was submitted to radical orchidectomy via the inguinal approach and high ligation of the spermatic cord. The anatomopathological examination revealed germ cell rhabdomyosarcoma of the epididymis with no testicular or spermatic cord involvement, which corresponded to stage I of the IRS classification (Intergroup Rhabdomyosarcoma Study). Its clinical and histological features and treatment are discussed.
