Respiratory Epithelial Adenomatoid Hamartoma: Expanding the Spectrum of Rare and Misleading Nasopharyngeal Lesions.

Respiratory epithelial adenomatoid hamartoma (REAH) is a rare benign lesion of the upper airway. It exceptionally affects the nasal cavity pathway. Its resemblance to other nasal masses poses diagnostic challenges. We report a case of REAH in a 59-year-old man presenting with left nasal obstruction and nocturnal snoring evolving over 2 years. Nasal endoscopy revealed a rhinopharyngeal mass, which was confirmed as REAH by histopathological examination of the biopsy performed under endoscopic guidance, resulting in complete lesion removal. Two years of follow-up showed no recurrence. This case is reported due to its rarity and the risk of misdiagnosis.
