title: Schistosomiasis of the urinary bladder in an African immigrant to North Carolina.
abstract: A 30-year-old black man came to the emergency department with gross hematuria, prostatitis, and urethritis 4 months after immigrating to this country from the Sudan in Africa. Urinalysis revealed hematuria and no ova or parasites. An intravenous urogram showed normal kidneys and ureters. The patient had cystoscopy with biopsies of an inflamed and ulcerated bladder mucosa. The nematode Schistosoma haematobium and schistosome eggs were identified without evidence of urothelial malignancy. The patient was treated with praziquantel and is currently asymptomatic. Over 200 million people are infected with schistosomiasis worldwide, yet this disease is rarely encountered in this country. The differential diagnosis and assessment of patients must include exposure to uncommon diseases that are endemic to other geographic regions.
