A Case of Erythema Nodosum Associated with Crohn's Disease / 대한피부과학회지

ABSTRACT

Erythema nodosum is known to be frequently associated with a variety of underlying diseases including drug reactions, infections, sarcoidosis and inflammatory bowel disease. Crohn's disease is an ulcerative, granulomatous, inflammatory disease which may have distinctive mucocutaneous manifestations. In most studies on Crohn's disease, 1 to 2% of the patients had at least one attack of erythema nodosum. However, erythema nodosum associated with Crohn's disease has not yet been reported in the Korean dermatologic literature. We report, herein, an 11- year-old male with Cronh's disease, who presented with erythematous, tender, subcutaneous nodules on his lower extremities. These showed histopathologic findings of erythema nodosum.
