Sjogren's syndrome occurs as an occasional complication of autoimmune hepatitis, and purpura or thrombocytopenia develops in some patients with this syndrome. This report describes a 62-year-old womanwith a 6-year history of autoimmune hepatitis who concurrently had hypergammaglobulinemic purpura, immune thrombocytopenia and Sjogren's syndrome. Treatment with prednisolone resulted in marked improvement of biochemical, hematological and dermatological abnormalities. This case emphasizes the manifestation of purpura or thrombocytopenia as an associated disorder during the course of autoimmunehepatitis concomitant with Sjogren's syndrome.
