Respiratory epithelial adenomatoid hamartoma on the anterior nasal septum

Respiratory epithelial adenomatoid hamartoma (REAH)is a rare benign lesion of the sinonasal cavity. In this report,by physical examination in the anterior part of thenasal cavity, on the septum a mass lesion was detectedand paranasal sinus computed tomography (PSCT) performed.On PSCT; bounded, homogenious, solid lesionwas shown and no evidence of invasion of surroundingbone and cartilage structures. Histopathologic diagnosisof the lesion was evaluated as REAH. Though REAH is avery rare benign lesion of sinonasal cavity the treatmentis only simple excision. Therefore keeping it in mind indifferential diagnosis list, aggressive surgical proceduresshould be avoided. The clinical and radiological featuresare discussed in the light of the literature.Key words: Hamartoma, sinonasal cavity, septum
