Orofacial granulomatosis as initial manifestation of Crohn's disease: a report of two cases.

Patients with Crohn's disease generally present with chronic diarrhoea and/or abdominal pain. However, it may be the extraintestinal manifestations as orofacial granulomatosis (OFG)--a rare syndrome with chronic swelling of the lips and the lower half of the face combined with oral ulcerations and hyperplastic gingivitis--that urge patients to seek medical advice. We report two rare cases in which swelling of the lips and cheeks were the initial symptoms that finally led to the diagnosis of Crohn's disease.
