ABSTRACT
Primary tracheobronchial amyloidosis (TBA) is a rare disease characterized by extracellular focal or diffuse submucosal deposits of amyloid proteins. Various types of endobronchial lesions have been described in TBA when bronchoscopy is performed using white light. Narrow-band imaging bronchoscopy has been mainly employed for detecting preneoplastic and neoplastic endobronchial lesions as it provides more detailed images of the microvasculature reflective of an altered angiogenesis process. Here, we describe bronchoscopic findings with white light and narrow-band imaging in 2 patients presenting with central airway obstructive disease later confirmed as having primary TBA.
