title: Hereditary multiple exostoses and cervical ventral protuberance causing dysphagia. A case report.
abstract: METHODS
  A case report of a patient with hereditary multiple exostosis and who presented with cervical ventral protuberance causing dysphagia.
  
  
  OBJECTIVE
  To present this rare situation and to discuss the treatment and the result obtained.
  
  
  BACKGROUND
  We found in the literature only one case of exostosis of the cervical spine causing dysphagia.
  
  
  METHODS
  The patient, a 16-year-old girl, was affected by hereditary multiple exostosis, as was her father. The diagnosis was confirmed by radiograph, computed tomography, and magnetic resonance imaging, which showed a tumor in the anterior arch of the atlas. The patient was submitted to a transoral approach, and the tumor was excised.
  
  
  RESULTS
  The patient had a good evolution 2 years after the surgery without sign of recurrence.
  
  
  CONCLUSIONS
  This was a very rare situation, and the result validated the treatment used.
