Surgical Treatment of Primary Tracheal Adenoid Cystic Carcinoma.

Primary tracheal adenoid cystic carcinoma (TACC) occurring in the cervical trachea and invading the thyroid is very rare. Surgical resection and airway reconstruction are the main treatment methods, and other treatments include radiotherapy and endoscopic intervention. Herein, we present the case of a 74-year-old female patient with TACC. The patient underwent surgery and postoperative pathology showed that the tumor invaded the adventitia of the trachea and bilateral thyroid, where nerve involvement was observed. The patient recovered well after the operation without adjuvant therapy. Eight months after the operation, Computed tomography showed that the trachea was unobstructed and there was no recurrence.
