title: Metastatic Crohn's disease of the umbilicus.
abstract: We report a case of metastatic Crohn's disease of the umbilicus which responded to topical corticosteroid treatment. Crohn's disease is a granulomatous disease of the bowel which may affect other organs. The skin is commonly involved, and the cutaneous manifestations may be non-specific, e.g. pyoderma gangrenosum or erythema nodosum, or specific with epithelioid granulomas and multinucleated giant cells in the skin. Specific skin lesions may be contiguous with the bowel at sites including the perineum, mouth and adjacent to fistulae, or separated from it by normal skin from the bowel, a rare condition which has been termed 'metastatic' Crohn's disease.
