A Case of Crohn? Disease Associated with Pyoderma Gangrenosum and Peripheral Arthritis / 대한류마티스학회지

ABSTRACT

The Crohn? disease is a inflammatory bowel disease and it? symptoms are nonspecific. The extraintestinal manifestations of Crohn? disease are arthritis, pericholangitis, erythema nodosum, pyoderma gangrenosum, uveitis, episcleritis, and miscellaneous. Arthritic manifestations caused by Crohn? disease belong to seronegative spondyloarthropathies and are divided into peripheral arthritis, spondylitis, and sacroiliitis. And peripheral arthritis in Crohn? disease usually worsen with exacerbation of bowel inflammation but pyoderma gangrenosum, the most severe skin lesion, bears little relationship to the activity or extent of the colitis. A 53 year-old man presented peripheral arthritis on multiple joints and necrotizing ulcerative skin lesion on abdomen and left knee. He had undergone T-loop colostomy due to recurrent anal fistula. Colonoscopy and biopsy of colonic mucosa showed Crohn? disease. We report a case of Crohn? disease associated with pyoderma gangrenosum and peripheral arthritis with relevant review of literatures.
