title: A case of respiratory epithelial adenomatoid hamartoma.
abstract: We report a case of a 70-year-old man diagnosed with a respiratory epithelial adenomatoid hamartoma (REAH) of the nasal cavity after a past sinus surgery and associated with nasal polyposis. REAH is a recently described pathologic entity that can present with nasal obstruction, congestion, rhinorrhea, epistaxis, hyposmia, and headaches. It is a rare lesion of nasal and paranasal sinuses, but should be considered in the differential diagnosis because it is a benign lesion and complete surgical resection is curative.
