Pyoderma gangrenosum-a complication of chronic venous leg ulceration?

Abstract

Three patients whose chronic venous leg ulcers were complicated by pyoderma gangrenosum are reported. Illnesses which may have predisposed to the development of pyoderma gangrenosum included Crohn's colitis, rheumatoid arthritis and small bowel perforation. Pyoderma gangrenosum should be suspected in susceptible patients whose venous leg ulcers undergo inexplicable and painful deterioration.
