[A case of tracheal benign mixed tumor].

A 44-year-old male was admitted because of dyspnea. Bronchoscopy revealed a tumor obstructing 85% of the tracheal lumen, at the site of the membranous portion, 3 cm below the vocal cords. The tumor was removed by sleeve tracheal resection with end to end anastomosis. Histological findings showed benign mixed tumor (pleomorphic adenoma) arising from the tracheal wall. Postoperative course was uneventful. Only 5 tracheal mixed tumors have been found in the Japanese literatures. Therapeutic approach to this tracheal tumor is discussed in this paper.
