[Urinary schistosomiasis: remarks on a case]

Urinary tract schistosomiasis is a parasitic disease caused by S. haematobium with a wide range of clinical manifestations related to the mucosal and submucosal granulomatous lesions of the bladder. It affects about 80 million people in Africa, Middle-East and India, while in Italy it is rarely seen among immigrants from endemic areas and returning travellers. The authors describe a case occurred in a 26 years old man, recently emigrated from a rural area of Ghana. He had the symptoms of a haemorrhagic cystitis. Cystoscopy and biopsy showed granulomatous lesions of bladder with calcified eggs. Microscopic examination of urine was positive for Schistosoma haematobium eggs. The therapy with Praziquantel (40 mg/Kg una tantum) was effective. The authors emphasized the risk of introduction of schistosomiasis in some regions of our country, in consideration of the presence of the intermediate host as well as of an appropriate climate.
