Abstract
A 71 year-old female developed wheezing and hemosputum. Bronchoscopy revealed elevated multiple whitish nodules in the submucosa of the trachea and left main stem bronchus. A 50 year-old male complained of hoarseness and productive cough. His lesion was confirmed by tomogram. Biopsy sections of both cases showed areas of osseous tissues in the submucosa. Specific treatment of this disease was unknown. A relationship between this disease and primary tracheobronchial amyloidosis has been proposed by Sakula, who suggested that this disease was an end stage of primary lung amyloidosis.
