Abstract

Respiratory epithelial adenomatoid hamartoma (REAH) is an uncommon non-neoplastic proliferation of the sinonasal tract that presents as a mass-like lesion. It can be confused with a variety of benign and malignant entities including inflammatory polyp, inverted papilloma and low-grade sinonasal adenocarcinoma. Misinterpretation may result in unnecessary radical surgery. Recently we have experienced two patients of REAH in the nasal cavity. One was originated from the lateral nasal wall and the other was from the both olfactory clefts. Therefore, we report these cases with a brief literature review.
