Respiratory Epithelial Adenomatoid Hamartoma of the Nasal Septum

Objective: Hamartomas are relatively uncommon, non-neoplastic malformations indigenous to the involved anatomic site. Respiratory epithelial adenomatoid hamartoma (REAH) is a subset of hamartoma characterized by prominent glandular proliferation lined by ciliated epithelium originating from the surface epithelium. Their location in the nasal cavity is rare and when present, mostly associated with the posterior nasal septum. We present such a case arising from the anterior nasal septum. Methods: Design: Case report Setting: Tertiary University Referral Center Patient: One Results: A 32-year-old lady who presented with a long-standing nasal block was found to have a broad-based nasal mass arising from the left anterior nasal septum. The lesion was histologically diagnosed as respiratory epithelial adenomatoid hamartoma following surgical excision. Conclusion: Respiratory epithelial adenomatoid hamartoma although rare must be taken into consideration in the differential diagnosis of nasal lesions.
