title: [Skin diseases associated with chronic hepatitis C].
abstract: The authors are discussing hepatic and extrahepatic pathologic processes caused by hepatitis C virus (HCV) infection and they focus their interest to the skin disorders appearing in the presence of chronic, active HCV infections. The trigger of the immunologic processes leading to dermatologic manifestations are the activated T cells (CD8 + cytotoxic T lymphocytes), cytokins, and also the expansion of certain B cells. Pathologic immunologic phenomena may initiate various dermatologic manifestations. Immunoglobulins, immuncomplexes generated by the disease itself are manifested as various forms of cutan vasculitis. In the present series of patients (pts), HCV related skin disorders known from the literature were diagnosed in eleven cases and they were representing 7 different disease entities. These were palpable purpura (3 pts), urticaria, prurigo and alopecia areata (2-2 pts), lichen ruber planus, pruritus and vitiligo (1-1 patient respectively). The case reports of 2 pts, one with palpable purpura (vasculitis purpurica), one with prurigo and vitiligo are presented in details.
