Amyloidosis in the upper aerodigestive tracts.

The upper aerodigestive tracts, particularly the larynx, are not uncommon repositories for amyloid. In most instances amyloidosis of the larynx is localized and is not associated with or followed by systemic disease. Oral and nasopharyngeal amyloidoses, on the other hand, are very often manifestations of systemic predisposing disorders. Laryngeal amyloidosis is treated, when indicated, by surgical removal, often repeated because of persistence or multifocal deposits.
