Nasopharynx Hairy Polyp as a Cause of Stridor in Newborn.

Hairy polyps are histological benign lesions derived from 2 germinal layers which arise during fetal period, they can occur anywhere in the body. When they are localized in the oropharynx or nasopharynx can lead to upper airway obstruction in infants.We describe a case of a 2-days-old full-term female with intermittent upper airway obstruction, stridor, and feeding difficulty. Endoscopic and radiologic exams show a mass localized in nasopharynx, which was excised with a transnasal endoscopic approach resolving her respiratory difficulties.Histology confirmed the diagnosis of hairy polyp, a mass composed by an external layer of mature skin and a core with subcutaneous mature fibro fatty tissue, mature skeletal muscle, and cartilage.This report has an important value for the readers because, for a good functional result and an excellent prognosis, an accurate clinic and radiologic diagnose, with subsequent surgical complete resection should be performed.
