Localized tracheobronchial amyloidosis: A rare case presentation and tailored management approaches

Localized tracheobronchial amyloidosis (TBA) is a rare manifestation of pulmonary amyloid disease, and can result in central airway obstruction. The nature of presentation is variable and there may be a delayed diagnosis. TBA has a variable prognosis and the most commonly used strategy for management is airway recanalization. Here, we describe the tailored management approach for a 64‐year‐old Caucasian female presenting with localized TBA of the left main bronchus. Pulmonary function testing, computed tomography and positron emission tomography results are detailed. Rigid bronchoscopy was utilized for diagnostic and therapeutic intervention, which involved debulking and stent insertion. Amyloid deposition and localized inflammation were identified through histopathology. Focal external beam radiation therapy was administered following multidisciplinary discussion and review of the literature, with no evidence of active disease at 6 months follow‐up.
