Amyloidosis limited to the tracheobronchial respiratory tract is a relatively rare condition. Fewer than 100 cases of tracheobronchial amyloidosis are reported. It is characterized by deposits of amyloid in airway walls. Bronchoscopy, although carrying a risk of bleeding, is the procedure of choice diagnostically and therapeutically. 49-year old man suffered from cough and exertional dyspnea over 20s years and recently hemoptysis, atelectasis of right middle lobe and postobstructive pneumonia.
