Laryngotracheal Amyloidosis Presenting as a Laryngeal Mass - Abstract
Amyloidosis is a disease caused by improper three-dimensional folding of precursor proteins, which results in formation of protein aggregates, amyloid fibrils, that cause cell and organ damage. Amyloidosis localized to the respiratory tract is considered rare, with a spectrum of clinical symptoms. We report a case of a 72 year old man who presented with a laryngeal mass, found to be an amyloidoma. Cross-sectional imaging revealed disease involving the tracheobronchial tree. Despite its rarity, amyloidosis may be included in the differential diagnosis for diffuse nodularity and thickening involving the laryngeal folds and the tracheobronchial tree.
