[A rare tracheal malignant tumor: mucoepidermoid carcinoma (a case report)].

An 18-year-old male preferred to our clinic with hemoptysis, cough, dyspnea and stridor. A wide-based polypoid tumor that was localized at the right wall of the distal trachea was observed over 3 cm from the carina by flexible bronchoscope. Computerized tomography showed an intraluminal soft tissue density mass in the trachea. Though right thoracotomy, a tracheal resection that contains three rings of the trachea with malignant lesion was performed. Pathologic examination reported a tracheal mucoepidermoid carcinoma. The patient is alive without recurrence three years after surgery.
