Metastatic cutaneous Crohn's disease, in which noncaseating granuloma infiltration of the skin occurs at sites separated from the gastrointestinal tract by normal tissue, is the least common dermatologic manifestation of Crohn's disease. We report a case of a 34-year-old man with metastatic Crohn's disease presenting as prepuce and scrotal edema with typical histopathologic features. We think that any unusual cutaneous lesion in patients with Crohn's disease should be biopsied.
