The World Health Organization estimates that more than 400 million people are infected with either hepatitis B virus or hepatitis C virus while approximately 150 million have chronic hepatitis C. Viral hepatitis, specifically hepatitis B and hepatitis C, not only causes liver disease but also can present with extrahepatic manifestations, including cutaneous lesions. Among all extrahepatic manifestations of liver diseases, cutaneous manifestations are the most common. In addition, they are easily recognizable and may provide the first clues of liver disease. Serum sickness and polyarteritis nodosa are the main cutaneous manifestations related to hepatitis B virus infection. Cutaneous manifestations related to hepatitis C virus infection include mixed cryoglobulinemia, porphyria cutanea tarda, and lichen planus. In addition, the appearance of adverse cutaneous reactions both local and diffuse is frequent during the treatment of hepatitis C virus infection.

Characterized by the presence of cryoglobulins in the serum. This may result in a clinical syndrome of systemic inflammation caused by cryoglobulin-containing immune complexes.
Yellowish discoloration of the skin, white of the eyes, and mucous membranes caused by deposition of bile salts in the tissues.
Inflammation of the liver, caused by a virus or a toxin and characterized by jaundice, liver enlargement, and fever.
