Schistosoma haematobium: A Delayed Cause of Hematuria

A 22-year-old African American man with recurrent episodes of gross hematuria for 6 months presented to the clinic for evaluation. A thorough history revealed that the patient emigrated from Mozambique to the United States 12 years ago. Urine culture was negative for a urinary tract infection. Cystoscopy revealed 4 lesions in the bladder. Biopsy of the bladder lesion revealed severe cystitis and Schistosoma haematobium. The patient later confirmed that he used to swim in rivers and streams back in Africa. He completed a course of praziquantel and his gross hematuria resolved.
