title: Primary tracheobronchial amyloidosis.
abstract: Tracheobronchial amyloidosis is an uncommon localized form of amyloidosis, characterized by amyloid deposits restricted to the trachea, main bronchi and segmental bronchi. We present the case of a retired 67-year-old man with long-term progressive dyspnea, wheezing and chest pain. A diagnosis of tracheobronchial amyloidosis was made after the third fiberoptic bronchoscopy and histological confirmation through Congo red staining of tissue samples.
