Abstract

Autoimmune pancreatitis is a distinct entity with characteristic histologic, morphologic, and clinical features. It may be isolated or associated with Sjögren syndrome, primary biliary cirrhosis, primary sclerosing cholangitis, Crohn's disease and ulcerative colitis, or other immune-mediated disorders. Recent studies have reported the profiles of autoantibodies in autoimmune pancreatitis. Also a number of reports on single cases or small series of cases have been published. We report three cases of autoimmune pancreatitis; one case was associated with primary sclerosing cholangitis, which was misdiagnosed as pancreatic cancer; the other two cases were improved with steroid therapy.
