[Pseudo-tumoral form of urinary bilharziasis in a child].

A tumor-like form of urinary schistosomiasis is reported. Diagnosis was established intraoperatively. The finding of hematuria and of a stay in an area where schistosomiasis is endemic suggested the diagnosis but specific investigations were negative. Cystoscopy revealed a budding, hemorrhagic tumor lying against the posterior aspect of the bladder with no other lesions suggestive of schistosomiasis. The true prevalence of these tumor-like forms of urinary schistosomiasis is analyzed. Emphasis is put on the need for using several investigations to reach the correct diagnosis.
