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.

Bronchoscopy has been described as a safe procedure with a low rate of complications. We present a case of a 48-year-old woman who underwent flexible bronchoscopy for chronic cough. Immediately after the procedure, she developed proptosis of the left eye that required urgent attention. It resolved with medical treatment alone and the patient was discharged without any long-term complications.
