title: Respiratory epithelial adenomatoid hamartomas of the sinonasal tract.
abstract: We report the clinicopathologic features of two cases of respiratory epithelial adenomatoid harmartoma (REAH) of the sinonasal tract. Hamartomas are rare in the nasal cavity. Histologically, these lesions were characterized by a glandular proliferation lined by ciliated respiratory epithelium originated from the surface epithelium. The two patients were evaluated by a gastroenterologist to assess intestine colocalization. The treatment was a complete surgical resection through limited approach. We should be aware of this entity as a differential diagnosis for inverted papilloma and well-differenciated adenocarcinoma. Fine histopathological analysis is necessary to avoid aggressive surgery for this benign lesion.
