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.
