Tracheobronchial amyloidosis treated by endobronchial laser resection and self expanding Y stent.

Amyloid deposition in tracheobronchial tree is a rare presentation and counts about 1% of benign tumors in this area. Herein, we describe a case of primary tracheobronchial amyloidosis which obstructed almost completely the distal trachea and the main left bronchus. The mass was successfully resected by mechanical resection and Nd-YAG laser coagulation during rigid bronchoscopy. Afterwards, a self-expanding Y-stent of new generation was inserted to restore airway patency. Five months later, radiological and bronchoscopic findings showed the stent in site, with normal patency of the tracheo-bronchial tree.
