Localized pulmonary amyloidosis without systemic involvement differentiates as nodular parenchymal opacities, diffuse parenchymal opacities, or tracheobronchial amyloidosis (TBA). TBA is a condition mostly seen in males aged up to 50–60 years, accounting for approximately 1% of benign lesions in the tracheobronchial tree. TBA is characterized by the accumulation of the amyloid material comprising immunoglobulin light chain (AL), which are observed as submucosal plaques and/or polypoid tumors; progressive form of tracheobronchial amyloidosis can lead to airway obstruction. Repeated excisional treatments, mainly laser treatment is preferable to open surgery. Here, we have presented the case of a patient diagnosed with the rarely occurring localized TBA.
