title: Metastatic Crohn's disease of thigh and forearm.
abstract: Cutaneous involvement with Crohn's disease at a site separated from the gastrointestinal tract by normal skin is termed metastatic Crohn's disease. Such a complication is extremely rare and previous reports have emphasised the flexural distribution of the ulcerated lesions. We report a patient who developed Crohn's disease involving the skin of the thigh and forearm several months after a panproctocolectomy for colorectal Crohn's disease.
