Watchful waiting in laryngo-tracheobronchial amyloid: A case report.

We report the long term follow up of a now 66-year-old male with laryngo-tracheobronchial amyloidosis. The patient initially presented with dysphonia and dyspnoea. He was diagnosed with laryngeal reflux and asthma. Seven years later, the patient underwent cross sectional thoracic imaging showing diffuse thickening of the distal trachea and proximal main bronchi. The patient's FEV1 and FVC remained stable over 13 years and no intervention was required.
