Hairy polyps: A new case presentation and a pathogenetic hypothesis.

Hairy polyps are benign lesions found in the oropharynx or nasopharynx that are thought to be present at birth and can lead to upper airway obstruction in infants. Also known as naso-oropharyngeal choristoma, they are increasingly viewed as aggregates of bigeminal tissue, likely from the first or second branchial arches, found in aberrant locations. They are benign lesions that are usually successfully treated by surgical excision. Here we present a rare case of a hairy polyp originating in the eustachian tube of a 7-week-old male, discuss our management of the patient, and put forth a new hypothesis as to the origin of these lesions.
