title: A rare case of hematuria.
abstract: The infestation by Schistosoma haematobium is common in African countries and West Asia. Its chronic phase is characterized by the deposition of eggs of the parasite in various tissues of the body causing inflammatory response, formation of granulomas and fibrosis. The disease often affects the urinary tract, presenting with hematuria and, in the terminal stage, renal failure by urinary obstruction and bladder squamous neoplasia. Since chronic infection can lead to significant morbidity, it is imperative that the physicians who serve this immigrant population become familiar with this disease. A case of an immigrant boy from Guinea-Bissau seen in a Nephrology appointment for monosymptomatic terminal hematuria is presented. The diagnosis of urinary schistosomiasis was confirmed by parasitological examination of urine and the pathological examination of bladder biopsies. After therapy with praziquantel, the patient became asymptomatic.
