Abstract
A 61-year-old woman was admitted to the hospital because of dyspnea. There was a previous history of undergoing a thyroidectomy for a thyroid tumor at elsewhere. On admission, airway stricture sound was heard at her throat, and respiratory function tests revealed a mixed ventilatory dysfunction. CT scan of the neck demonstrated a solid mass with clear margin that occupied about 90 percent of the tracheal lumen. Laryngeal fiberscopy showed an easy-bleeding tumor that nearly obstructed the tracheal lumen. A resection of trachea from first ring to fifth ring with end-to-end anastomosis was performed. Histologically, the tumor was cystic adenoid carcinoma arising from the tracheal gland. It penetrated the tracheal wall and extended the adjacent tissues. Postoperative radiation therapy with total dose of 50 Gy was given. She has been well without any signs of recurrence for 1 year after the operation.
