A Case of Hamartoma of the Subglottis / 대한이비인후과학회지

Hamartoma is a developmental anomaly or non-neoplastic malformations composed by an excessive growth of indigenous mature tissue present in wrong proportions and abnormal arrangements. Hamartomas may develop in all areas of the body but it is extremely rare in the larynx. The treatment of hamartomas consists of adequate surgical excision leading to an excellent prognosis. We present an incidentally detected subglottic mass during intubation in a 70-year-old male patient. The mass was excised by transoral laser surgery. Histopathologic examination of the lesion revealed that it consisted of hamartoma.
