Background: Tumors of the trachea are rare despite their histologic similarity to tumors of the main stem bronchus and lung. Materials and methods: Fourteen patients with tracheal tumor underwent surgical, radiational, or laser photocoagulation therapy from March 1981 to July 1996. Nine patients were malignant and five patients were benign. The most common malignant tumor was adenoid cystic carcinoma. Results: Age ranged from 10 to 65 years with mean age of 45.9 years. Most tumors were located middle and lower one-third of trachea. Surgery was done through collar incision, or collar incision with vertical partial sternal division, or left posterolateral thoracotomy, or sternal division with laryngeal release. Two patients died after operation, because of the disruption of anastomosis and airway obstruction,and laryngeal edema after suprahyoid release. Only one patient died after 8 month of diagnosis. The other patients were doing well during the follow-up period.
