[Genitourinary bilharzioma. Isolated cases of vesical bilharzioma and epididymal bilharzioma].

The authors report on two isolated cases of bilharzioma: one vesical revealed by an hematuria and one epididymal constituting an intrascrotal mass. Clinical signs did not oriented toward these diagnosis and biology was helpless. Serodiagnosis by hemagglutination was negative, but immunofluorescence was more reliable. On the contrary both tumors were detected by echotomography of which the efficiency is determinant for the diagnosis and must be underlined. Only anatomopathology was able to confirm the diagnosis of tumor. As a matter of course, surgical exploration and excision are necessary in these types of tumors with negative biology. In both cases, effects were isolated. In one patient, infestation was old and already treated; in the second one, infestation was probably light. The authors recall also bilharzioma physiopathology. Frequency of vesical bilharzioma is about 20% of genito-urinary schistosomiasis while epididymal bilharzioma reaches only 0.29 to 4.8%. Direct line between bilharzioma and cancer is likely but controversial, schistosomiasis beeing a true irritative agent.
