Hamartoma is non-neoplastic malformation of tissue characterized by an abnormal mixture of tissues. It can occur in any area of the body, especially in the lung, kidney, and intestine. Respiratory epithelial adenomatoid hamartoma (REAH) is an uncommon lesion in nasal cavity. It is important to differentiate REAH from other neoplasm, including adenocarcinoma and inverted papilloma because misdiagnosis can lead to aggressive surgery. We report a case of REAH in nasal septum diagnosed on histopathology.
