Beware the respiratory epithelial adenomatoid hamartoma-a malignant masquerador.

Respiratory epithelial adenomatoid hamartoma (REAH) is a rare benign tumour, which can masquerade as a sinonasal malignancy. Commonly arising from the posterior nasal septum, we present the second described case of a lateral nasal cavity wall REAH in a 68-year-old male with a 2-year history of progressive left nasal obstruction. Clinical and radiological assessment predicted malignancy; however, histopathology identified a benign pathology. He was subsequently treated with narrow local excision under general anaesthetic with no evidence of recurrence at post-operative intervals.
