[A case of benign mixed tumor of the trachea].

A very rare case of benign mixed tumor of the trachea was reported. A 52-year-old male was admitted to our hospital because of hemoptysis, slight dyspnea and stridor. Bronchoscopic examination revealed a polypoid tumor which arose from the anterior wall of the upper trachea, obstructing about 70% of the tracheal lumen. For the purpose of getting pathological specimen and securing the air way in anesthesia, endoscopic polypectomy (2/3 of the tumor) was done by using GIF-XP 20. Circumferential resection of the trachea (4 rings) with end-to-end anastomosis was performed one month after polypectomy. To our knowledge, this was the 7th reported case in Japan. Clinical studies and operative procedures of this disease were briefly discussed.
