A Case of Pyoderma Gangrenosum Complicating Crohn's Disease / 대한소화기내시경학회지

ABSTRACT

Pyoderma gangrenosum is a rare chronic cutaneous disease with distinctive clinical characteristics. A painful nodule or pustule breaks down to form a progressively enlarging ulcer. The diagnosis is confirmed by exclusion of other diseases that may cause cutaneous ulcers. Associated conditions are common. The most common associated conditions are inflammatory bowel diseases, arthritis, hematologic disorders. Pyoderma gangrenosum develops in approximately 3~5% of patients with ulcerative colitis and 1% of patients with Crohn's disease. Until now, only one case of pyoderma gangrenosum associated with Crohn's disease has been reported in Korea. Recently, we experienced a case of pyoderma gangrenosum developed in a patient with Crohn's disease.
