Primary biliary cirrhosis and autoimmune hepatitis switch over: report of 2 cases.

Overlap syndrome in Autoimmune liver disease is not unusual but the switch over from one type of autoimmune liver disease to another is not well recognized. We report 2 cases of primary biliary cirrhosis (PBC) who with time, crossed over to autoimmune hepatitis (AIH). Recognition of such switch over from PBC to AIH is important for appropriate change in management of the patients.
