Respiratory epithelial adenomatoid hamartoma (reah) The h&e shows typical histologic findings of respiratory epithelial adenomatoid hamartoma, characterized by proliferation of medium sized glands with cilia surrounded by thickened basement membrane. Respiratory epithelial adenomatoid hamartoma (reah) is a benign entity characterized by an abnormal proliferation of glandular tissue surrounded by a thick eosinophilic basement membrane within ciliated respiratory epithelium with no evidence of atypical or metaplastic changes in the squamous cells.

The nasal cavity, particularly the posterior nasal septum, is the most common site of involvement It usually occurs unilaterally and can be cured with conservative surgical resection. Respiratory epithelial adenomatoid hamartoma (reah) is an uncommon lesion of the upper aerodigestive tract It is characterized by abnormal glandular formations with ciliated epithelium arising from the nasal cavity, paranasal sinuses and nasopharynx, but other locations have also been described.
