A Case of Endotracheal Hamartoma in a Long-term Hemodialysis Patient

Abstract

Only 8 cases of endotracheal hamartoma have been reported in the world literature, including the present case. A 63 year old male was referred to our hospital with a chief complaint of stridor. He had undergone hemodialysis for 10 years. Chest X-ray suggested a mass in the upper trachea and tomography indicated that the lesion was protruded from the left wall of the trachea. Bronchoscopy revealed an apparently polypoid tumor at the upper part of the trachea. Histological examination of the biopsy specimen suggested tracheal chondroma. However the autopsy findings yielded a diagnosis of endotracheal hamartoma. which contained some other components.
