Pyoderma Gangrenosum Developing After Total Colectomy Due to Ulcerative Colitis

122 yoderma gangrenosum (PG) is rarely seen; destructive, inflammatory skin disease characterized by painful nodules or pustules that progress to large and extended ulcerations.1 In 50% of the patients with PG, there is an underlying disease. These include inflammatory bowel disease, arthritis, leukemia, hepatitis, primary biliary cirrhosis, intestinal malignancies and monoclonal gammopathy. In the patients with ulcerative colitis (UC), the presence of PG is independent from the activity of the disease. However, rarely, activation of UC may lead to PG development. In this article, we present an UC case with arthritis and the lesions consistent with PG around ileostomy and on his right back, which have been developed approximately 7 months after total colectomy.
