BackgroundUrinary schistosomiasis is a common parasitic disease in endemic countries.Case presentationWe report the case of a patient who was on a working trip to Mauritania. This parasitosis, suspected in the presence of hematuria and the notion of stay in an endemic zone, was confirmed by the presence of Schistosoma heamatobium eggs during the histological examination of the bladder biopsy performed after cystoscopy, highlighting a bilharzial granuloma and of course, the diagnosis was confirmed by the presence of eggs during the direct examination of the freshly collected urine.ConclusionsIt should be pointed out that the diagnosis of schistosomiasis must be evoked with the association of hematuria and the particular inflammatory aspect of the vesical mucosa and, of course, the notion of stay in an endemic zone.
