Primary tracheobronchial amyloidosis--two case reports.

Primary tracheobronchial amyloidosis is a form of respiratory amyloidosis, characterised by insoluble amyloid fibril proteins deposits along the airways wall. It is an uncommon disease, requiring a tissue sample to establish the definite diagnosis based on specific pathological features. The authors report two cases of tracheobronchial amyloidosis, describing their symptoms and the diagnostic and therapeutic procedures that were performed.
