Respiratory Epithelial Adenomatoid Hamartoma Originating from Nasal Septum
A 23-year-old man with a history of obstruction of both nasal passages visited our office. Symptoms first developed about 10 years previously. The patient had undergone a nasal polypectomy 7 years before the current presentation. Nasal endoscopy revealed bilateral nasal polyposis in the middle meatus (). A CT scan of the paranasal sinus showed soft tissue density in all sinus cavity and both middle meatus (). A pre-operative punch biopsy of the mass suggested the diagnosis of REAH. Under general anesthesia, functional endoscopic sinus surgery was performed. Left nasal cavity mass originated from posterior aspect of nasal septum and mass was removed without remnant. Pathology of left nasal cavity mass revealed REAH associated with nasal polyposis and right nasal cavity polyp revealed chronic inflammation. There was a glandular proliferation originating from the surface epithelium (). The gland was lined by ciliated respiratory epithelium (). There were no postoperative complications. At 1-year follow-up, there was no evidence of recurrence.
