[Idiopathic granulomatous appendicitis or Crohn's disease confined to the appendix?]

Crohn's disease limited to the appendix is uncommon. When Crohn's disease affects the appendix it typically has a longer clinical course than most cases of acute appendicitis. The diagnosis is histological. Appendiceal Crohn's disease has a benign course after surgery, and that's why some authors believe that it could be a different entity which should be better addressed to as "Idiopathic Granulomatosus Appendicitis". We present three new cases of Crohn's disease limited to the appendix.
