title: Cheilitis granulomatosa associated with allergic contact dermatitis to betel quid.
abstract: Cheilitis granulomatosa (CG) is a rare disorder of unknown origin, which is characterized clinically by painless, recurrent or persistent swelling of 1 or both lips. Betel quids, composed of betel nuts (seeds of the Areca catechu), slake lime, and Piper betel leaf/or Piper betel inflorescence, are widely used in Asia and strongly associated with oral mucosal disease. It has also been found to be a cause of contact leukomelanosis because of its ingredients of various chemicals. We describe a case of CG induced by betel quid chewing.
