Concomitant occurrence of pyoderma gangrenosum and erythema nodosum in inflammatory bowel disease

Abstract

Erythema nodosum and pyoderma gangrenosum are common skin manifestations in inflammatory bowel diseases. Curiously, these two cutaneous features have seldom been reported to occur simultaneously. We present three patients affected with inflammatory bowel disease with concomitant erythema nodosum and pyoderma gangrenosum.
