Primary diffuse tracheobrochial amyloidosis: case report.

ABSTRACT

Respiratory amyloidosis is a rare disease that occurs in three forms tracheobronchial, nodular parenchymal and diffuse parenchymal involment. Tracheobronchial amyloidosis is characterized by focal or diffuse deposition of amyloid in the submucosa of the trachea and proximal bronchi. Herein, we report a case of diffuse tracheobronchial amyloidosis with plain radiography and thorax computed tomography findings.
