Abstract
Primary localized amyloidosis of the airways is an uncommon disorder characterized by amyloid deposits in the airway mucosa. In contrast to systemic amyloidosis other organs are not involved. Among the entities of airway amyloidosis, tracheobronchial amyloidosis is comparatively the most common subtype in the lower respiratory tract and laryngeal amyloidosis in the upper respiratory tract. The pathophysiology of localized airway amyloidosis is poorly understood. The clinical presentation is variable and often non-specific. No general consensus exists with regard to optimal treatment resulting in a variety of modalities used in clinical practice to manage this disorder. We report the case of a 50 year old woman with multifocal localized amyloidosis of the tracheobronchial tree and the upper airways. Tracheobronchial amyloidosis was treated with endoscopic debulking and external beam radiation, sinunasal amyloid deposits were surgically excised and are currently under surveillance. The importance of this extremely rare case lies in the multifocal presentation of an uncommon disorder requiring a multidisciplinary approach to offer optimal treatment including external beam radiation.
