[2 cases of unexpected anatomopathological discovery of a leiomyoma of the urogenital system].

The authors report their recent experience in two cases of leiomyoma of the genitourinary tract not only because of relatively low incidence of this neoplasm in such sites, but especially since in the first case a previous urothelial lesion had led to the performance of a cystectomy and bilateral uretero-ileo-cutaneostomy, which led us to attribute the later urethral lesion also to a transitional-type neoplastic site; in the second case, symptomatologic evolution, palpation and scrotal echography aroused suspicion of testicular neoplasm and only the observation during surgical operation made it possible to decide for a testis-preserving therapy enabled by the reassuring extemporaneous histological report.
