Metastatic Crohn's disease

Abstract

Metastatic Crohn''s disease is a term used to describe a granulomatous reaction occurring in flexures, and separated from the affected areas of the gastro-intestinal tract by normal skin. Previous reports refer to such lesions affecting the groins, the male genitalia, a flexture on the anterior abdominal wall of an obese patient, and submammary regions. A further case, in which the retro-auricular areas are involved, is presented.
