[Schistosomiasis mansoni in the seminal vesicle].

In endemic regions, Mansoni schistosomiasis is responsible for high morbidity-mortality rates due to diseases associated with infestation of the hepatic system. Genital involvement caused by Mansoni schistosomiasis is rare. We report the first case of Mansoni schistosomiasis in the seminal vesicle, which was diagnosed incidentally by means of histopathological study of the prostate and seminal vesicles after surgical removal.
