Respiratory Epithelial Adenomatoid Hamartoma Originating from Nasal Septum

초록

Respiratory epithelial adenomatoid hamartoma (REAR) is a rare benign lesion in nasal cavity We report two cases of REAR of the nasal cavity arising from nasal septum. The etiology of REAR is unknown although inflammation may induce gland proliferation observed in hamartomas. One of our cases was associated with nasal polyposis. REAR is a self-limiting disease, so it is important to differentiate REAR from other pathologic process, including inverted papilloma and low-grade adenocarcinoma. The treatment of choice is complete excision through a conservative approach.
