Endobronchial appearance of tracheobronchial amyloidosis. A case report and suggested classification.

Tracheobronchial amyloidosis with the co-existence of submucosal plaques and tumour-like masses is reported. The subdivision of tracheobronchial amyloidosis into submucosal plaques and tumour-like masses is questioned since there appears to be no difference in their clinical presentation and pathological appearance. It is suggested that lower respiratory tract amyloidosis should be classified into tracheobronchial, nodular parenchymal and diffuse alveolar septal amyloidosis.
