title: Cutaneous manifestations of viral hepatitis.
abstract: There are several extrahepatic cutaneous manifestations associated with hepatitis B and hepatitis C virus infection. Serum sickness and polyarteritis nodosa are predominantly associated with hepatitis B infection, whereas mixed cryoglobulinemia associated vasculitis and porphyria cutanea tarda are more frequently seen in hepatitis C infection. The clinico-pathogenic associations of these skin conditions are not completely defined but appear to involve activation of the host immune system including the complement system. Management of the aforementioned cutaneous manifestations of viral hepatitis is often similar to that done in cases without viral hepatitis, with control of immune activation being a key strategy. In cases associated with hepatitis B and C, control of viral replication with specific antiviral therapy is also important and associated with improvement in most of the associated clinical manifestations.
