title: Laparoscopic appendectomy for Crohn's disease of the appendix presenting as acute appendicitis.
abstract: BACKGROUND
  Crohn's disease confined to the appendix is rare but has been well described in the literature. It can mimic acute appendicitis clinically. After surgical treatment, recurrences of Crohn's disease are rare. We report the first case of treatment by laparoscopic appendectomy of Crohn's disease confined to the appendix.
  
  
  METHODS
  A healthy 32-year old man presented with a week-long history of vague lower abdominal pain. Diagnostic work-up, which included CT, enteroclysis, and routine blood work, revealed a patent appendiceal lumen with an inflammatory mass in the right lower quadrant.
  
  
  RESULTS
  Diagnostic laparoscopy revealed an inflamed appendix, and a laparoscopic appendectomy was performed, with frozen-section examination revealing Crohn's disease of the appendix. Two years after surgery, the patient has not had a recurrence of symptoms.
  
  
  CONCLUSIONS
  Crohn's disease of the appendix can mimic acute appendicitis, although often with a more indolent course. The disease may be treated successfully by laparoscopic appendectomy, with good long-term results.
