title: Hairy polyp of the oropharynx in association with a first branchial arch sinus.
abstract: OBJECTIVE
  Hairy polyps are rare, congenital malformations of the oropharynx and nasopharynx. To date, approximately 145 cases have been reported. However, the histogenesis of these lesions remains unclear.
  
  
  METHODS
  We report the case of a 2-day-old neonate presenting with a hairy polyp attached to the left palate, who re-presented aged 16 months with a discharging first branchial arch sinus.
  
  
  CONCLUSIONS
  We propose this case as supporting evidence for the theory that hairy polyps are a malformation of the first branchial arch system.
