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

ABSTRACT

Erythema nodosum is a reactive dermatosis that occurs in response to various stimuli, such as bacterial, fungal and viral infections, drugs, sarcoidosis and inflammatory bowel disease. Crohn's disease is a chronic inflammatory disorder of the gastrointestinal tract. Its etiology is unknown. It has been generally defined as a complex disease resulting from the interaction of multiple genetics and environmental factors. Erythema nodosum is the most common skin manifestation, occurring in about 1~15% of people with inflammatory bowel disease, particularly those with Crohn's disease. However erythema nodosum associated with Crohn's disease has been reported only rarely by Korean dermatologists. Herein, we report the case of a 31-year-old male with Crohn's disease who presented with erythematous, tender, subcutaneousnodules on his lower extremities
