[Hepatitis C virus-associated dermatoses: a review].

Acute infection with hepatitis C virus (HCV) is often clinically inapparent, but may affect several organ systems in its chronic course. In dermatology, common diseases such as lichen planus, cryoglobulinemic vasculitis and porphyria cutanea tarda have been described in association with HCV infection. A number of other dermatologic disorders, e.g., psoriasis, chronic urticaria, chronic pruritus, pseudo-kaposi sarcoma, necrolytic migratory erythema and Behçet disease, have been associated in case reports with HCV-induced liver disease. In this study we summarize the recent literature reports, present three patients observed by our group and update the topic.
