Hypergammaglobulinaemic purpura associated with alcoholic liver cirrhosis.

Hypergammaglobulinaemic purpura (HP) is commonly found in Sjögren's syndrome. We report a rare association of HP arising in a patient with alcoholic liver cirrhosis. A 65-year-old man presented with palpable purpura on the legs. Histological examination of a biopsy taken from the purpura found leucocytoclastic vasculitis in the superficial and mid-dermis. The activity of the vasculitic skin lesions correlated with liver dysfunction. Increased IgA and IgG levels, and hypocomplementaemia, may account for the pathogenesis of the hypergammaglobulinaemic immune complex-mediated vasculitis in this case.
