Rationale: Ulcerative colitis (UC) is an inflammatory bowel disease (IBD) characterized by continuous inflammation of the colonic mucosa. Autoimmune hepatitis (AIH) a chronic liver hypergammaglobulinemia, circulating autoantibodies, interface hepatitis, and favorable response to immunosuppression. An association between IBD AIH uncommon, experts have suggested that in patients with overlapping AIH, anti-tumor necrosis factor agents can be used. Therefore, this study reports rare case patient...
