We report a case of a 50-year-old man diagnosed with a unilateral nasal mass found to be a respiratory epithelial adenomatoid hamartoma (REAH) upon pathologic examination.REAH is a recently described pathologic entity that can present with nasal obstruction, congestion, rhinorrhoea,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.
