Metastatic Crohn's Disease.

Metastatic cutaneous involvement is a rare extraintestinal manifestation of Crohn's disease. Presence of cutaneous noncaseating granulomas that are anatomically noncontiguous in location with a fistula or the gastrointestinal tract is a diagnostic hallmark. We present a case of inflammatory bowel disease initially diagnosed as ulcerative colitis, but later manifesting as intra-abdominal abscesses and ulcerated cutaneous lesions that on biopsy proved to be metastatic Crohn's disease. The patient promptly responded to corticosteroid therapy.
