Pericholangitis with Ulcerative Colitis Following Autoimmune Hepatitis over 12 Years

A 35-year-old woman was diagnosed as autoimmune hepatitis 12 years ago by abnormal findings of liver tests including lupus erythematosus (LE) cell phenomenon and liver biopsy. She was admitted in May 1990 with a history of lower gastrointestinal bleeding. Colonoscopy with biopsy and barium enema revealed chronic ulcerative colitis along the entir colon. Since liver tests did not respond well to prednisolone treatment, liver biopsy was again performed and it revealed periductal inflammation with small duct proliferation, a finding compatible with pericholangitis. We herein report this patient who was initially diagnosed as autoimmune hepatitis and thereafter found to be pericholangitis associated with ulcerative colitis.(Internal Medicine 31: 1228-1232, 1992)
