비전정에 발생한 간엽성 과오종 1예

Hamartomas are non-malignant malformations or inborn errors of tissue development characterized by haphazard arrangement and growth of tissue indigenous to the specific part of the body where they present. Hamartomas are more often found in the kidney, lung, or gastrointestinal tract, but very rarely originate in the nasal cavity and paranasal sinuses, especially in nasal vestibule. This report presents a case of a 47-years-old female with a right nasal vestibule mass, which was removed via a endonasal approach. Histopathological examination of the specimen was consistent with mesenchymal hamartoma. (J Clinical Otolaryngol 2007;18:108–110)
