title: [Diffuse tracheo-bronchial amyloidosis].
abstract: The case of a 52 year old man, whose initial clinical manifestations were dyspnea, bloodstained sputum and malaise is reported. After the initial cancer hypothesis, a diagnosis of diffuse primary tracheo-bronchial amyloidosis was made. The amyloid substance present was not of A A type and the plasma cells next to the deposits were polyclonal. The piece-meal removal of the masses by bronchoscopy led to profuse bleeding. The patient died with sepsis. The clinical, pathological and therapeutical aspects of lower respiratory tract amyloidosis are reviewed.
