Respiratory epithelial adenomatoid hamartoma in the nasal cavity.

We report a 65-year-old male with a hamartoma in the left nasal cavity. A mass was found in the left nasal cavity and was diagnosed as a benign tumor on the basis of preoperative findings. Left lateral rhinotomy was performed to completely remove it and the lesion was found to have arisen from the inferior turbinate. The pathological diagnosis was respiratory epithelial adenomatoid hamartoma. We discuss the pathological features of this disease.
