We have encountered and successfully treated thirteen cases of tracheobronchial amyloidosis using a laser. The clinical data, radiology, endoscopic and histological appearance of these patients were similar to that described in the literature (48 published cases). A YAG laser was used, introduced through a rigid bronchoscope. The principal difficulties of this type of resection were related to the oozing of blood which they caused. Only lesions in the trachea, main and lobar bronchi could be destroyed. 8 of the 9 patients followed for sufficiently long were clearly improved but a patient whose lesions were very diffuse did not experience any benefit. The laser seems to us above all to be indicated when there is considerable obstruction by amyloid, limited to the trachea and/or several of the major bronchi.

Introduction: Amyloidosis, a polymeric deposition disease classified according to protein subtype, may have varied pulmonary manifestations. Its anatomic-radiologic phenotypes include nodular, cystic, alveolar-septal, and tracheobronchial forms. Clinical presentation may range from asymptomatic parenchymal nodules to respiratory failure from diffuse parenchymal infiltration or diaphragmatic deposition.

Deposition of amyloid proteins in extracellular space can occur due to uncontrolled inflammatory processes. Tracheobronchial amyloidosis (TBA) is a rare form of such disease. A 68-year-old woman was evaluated for chronic cough following a COVID-19 infection.

Tracheobronchial amyloidosis is a rare condition characterized by the deposition of amyloid proteins in the trachea and bronchi, leading to significant respiratory symptoms such as chronic mucoid, cough, dyspnea, and recurrent respiratory infections. We present the case of a 61-year-old individual who developed tracheobronchial amyloidosis, which poses a diagnostic challenge due to its clinical and radiological resemblance to other pulmonary disorders, including chronic bronchitis. Histologically, tracheobronchial amyloidosis is characterized by the presence of amyloid deposits confirmed by Congo red staining, which shows apple-green birefringence under polarized light.

Pulmonary amyloidosis is an extremely rare disease, often detected incidentally because of its asymptomatic nature and potential to result in fatal outcomes. In this study, we aimed to present the clinical and radiological features of patients diagnosed with pulmonary amyloidosis by biopsy. This descriptive study included 21 patients with pathologically diagnosed pulmonary amyloidosis.
