Abstract

Cases sharing features of both primary biliary cirrhosis and autoimmune hepatitis have been reported as a mixed type, overlap syndrome, immunocholangitis and autoimmune cholangiopathy. A primary biliary cirrhosis- autoimmune hepatitis overlap syndrome is unusual and characterized by overlapping features; cholestasis, high titer of alkaline phosphatase, bile duct damage and granulomas in the liver biopsy, high antinuclear antibody, increased IgG and IgM and intra-acinar hepatitis with piecemeal necrosis. Autoimmune mechanisms are thought to play a major role in the pathogenesis of the overlapping syndrome and the bases of immunosuppressive therapy. A 58-year-old female patient shows overlapping clinical and laboratory findings, chronic active hepatitis in initial liver biopsy which transits to primary biliary cirrhosis with cholangitis and granulomas. This is a case of hepatobiliary lesion showing overlapping features of both primary biliary cirrhosis and autoimmune hepatitis over 3-year period.
