Hairy polyp of the oropharynx in association with a first branchial arch sinus

Abstract

AbstractObjectives: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.Case report: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.Conclusion:We propose this case as supporting evidence for the theory that hairy polyps are a malformation of the first branchial arch system.
