Abstract
A 50-year-old man presented to clinic with a two-year history of progressive exertional dyspnea and voice hoarseness. This history suggested upper airways obstruction, which was confirmed on computed tomography imaging that revealed extensive thickening of the proximal tracheal wall causing severe luminal narrowing. Bronchoscopic debulking was then performed and the samples obtained confirmed tracheal amyloidoisis. Extensive investigation confirmed that disease was localized solely to the trachea. Ultimately, after multiple discussions, the chosen treatment modality was radiotherapy, which proceeded relatively uneventfully and achieved excellent radiological and clinical response. Although tracheal amyloidosis is rare, it is most commonly observed as part of a multisystem presentation. The present report describes the even more uncommon diagnosis of isolated tracheal amyloidosis and highlights the role of radiotherapy in its management.
