title: Three cases of primary pulmonary amyloidosis.
abstract: In three cases of primary pulmonary amyloidosis the chief complaint was hemosputum. The diagnosis of amyloidosis was made using histochemical analysis of bronchial wall biopsy in all cases; multiple nodular lesions were observed in trachea and bronchi on flexible fiberoptic bronchoscopy. The surface of the tracheobronchial mucosa was smooth but bled easily. In one patient, chest X-ray film showed a solitary nodular shadow in the left lower lung field. These three cases were tracheobronchial amyloidosis, and one case was combined with nodular parenchymal type amyloidosis.
