Metastatic Crohn's disease. A rare cutaneous manifestation.

Cutaneous extraintestinal manifestations of Crohn's disease are common. Lesions contiguous with the gastrointestinal tract, such as perianal, peristomal, and perifistular inflammation are characterized by the histologic demonstration of granulomas. Rarely a cutaneous granulomatous lesion occurs that is noncontiguous with the gastrointestinal tract and is separated from it by normal skin.
