title: Localized vasculitis of the gastrointestinal tract.
abstract: OBJECTIVE
  Isolated vasculitis of the gastrointestinal (GI) tract is a rare entity. Endoscopic biopsies have low sensitivity to diagnose intestinal vasculitis, even though the endoscopic findings may be suggestive of this condition. Our aims were to describe a case of biopsy-proven colonic leukocytoclastic vasculitis and review the literature.
  
  
  METHODS
  A patient with biopsy-proven colonic leukocytoclastic vasculitis is described. A Medline database search of cases with localized GI vasculitis between January 1985 and September 2005 was conducted.
  
  
  RESULTS
  A 32-year-old man was admitted to the hospital because of abdominal pain and diarrhea. A colonic biopsy showed leukocytoclastic vasculitis. There are very few articles on leukocytoclastic GI vasculitis as a separate disease, and most of them emphasize the difficulty in classification. Unlike our case, in former cases of localized vasculitis a diagnosis was made after surgery. Although our patient had steroid-refractory biopsy-proven isolated intestinal vasculitis, treatment with intravenous cyclophosphamide resulted in rapid resolution of symptoms and surgery was not required.
  
  
  CONCLUSIONS
  In patients with abdominal pain a diagnosis of intestinal vasculitis should be considered. Immunosuppressive therapy allowed our patient to avoid surgery and may be similarly beneficial in other similar cases.
