title: [Bronchogenic cyst of the tongue in an adult].
abstract: BACKGROUND
  Choristoma are non-malignant embryonic tumors, defined by ectopic tissues different from the organ on which they develop. The bronchogenic cyst is a choristoma affecting the upper aero digestive tract. It is lined with respiratory epithelium. The tongue is a rare localization for choristoma.
  
  
  METHODS
  We report the case of a 22-year old male patient who consulted in maxillofacial surgery for painful macroglossia. Imaging revealed a median lesion, suggesting an abscessed embryonic tumor. Pathologic examination after surgical exeresis confirmed the diagnosis of lingual choristoma of the bronchogenic cyst type.
  
  
  CONCLUSIONS
  Embryonic tumors of the tongue are generally diagnosed during childhood. Adult cases are rare. Surgical removal is the only treatment. Post-operative complications and relapse are rare. Only one case of malignant transformation has been reported; systematic radical exeresis is thus always recommended.
