[Obstruction of the principal bile duct caused by Fasciola hepatica. First case in Sicily].

The first case of human liver infestation due to liver fluke in Sicily is reported. After a clinical review of parasitosis, the autochthonous nature of the case is mentioned to highlight its epidemiological and prophylactic importance, especially in those regions where climatic conditions and living and working habits favour infestation. Finally, attention is called to diagnostic difficulties, treatment and appropriate hygiene and dietetic measures.
