Hepatocellular disease in the giant-cell arteritis/polymyalgia rheumatica syndrome.

An elderly man developed temporal arteritis and polymyalgia rheumatica with coexisting biochemical abnormalities of liver function. Biopsy revealed hepatic changes which have not been previously reported. There was hepatocellular necrosis and inflammation together with a prominent hyperplasia of perisinusoidal lipocytes of Ito. Temporal artery biopsy confirmed the presence of granulomatous panarteritis. Corticosteroid therapy produced rapid resolution of symptoms and reversion of liver function tests to normal.
