Transient subcutaneous granulomatosis of the upper extremities in Crohn's disease
Abstract:
Skin lesions occur fairly commonly in patients with Crohn's disease of the colon (14%). Erythema nodosum and pyoderma gangrenosum are the most frequently recognized. Granulomatosis of the skin, continuous with bowel involvement, has been reported. Involvement of the subcutaneous tissue, discontinuous with intestinal disease, is unusual and we wish to report a case of Crohn's disease of the colon complicated by infraepidermal perivascular granulomas of the forearms. The lesions disappeared spontaneously.
