Abstract
Primary tracheal tumors are uncommon, making up only 0.2% of all respiratory malignancies. Adenoid cystic carcinoma (ACC) is the most common tumor, accounting for about 30% of primary tracheal tumors. It is often difficult to manage these tumors surgically, due to its expansion and submucosal invasion, and furthermore, due to the patient's condition. Thus, it is essential to perform palliative treatment in order to maintain the airway through and to control the progress. Herein, we report a case of ACC treated by repeated bronchoscopic argon plasma coagulation (APC) as palliative therapy.
A 71-year-old Japanese male was referred to our hospital's emergency department for dyspnea. Bronchoscopic examination revealed expanded intraluminal obstructive bronchial tumors from the left bronchus to right. The patient had undergone bronchoscopic APC treatment several times. The obstruction was improved, and no worsening was seen for 26 months. Repeated bronchoscopic APC as a palliative therapy is promising and useful therapy without heavy adverse reactions to control the tumor growth.
