ABSTRACT
Amyloidosis limited to bronchopulmonary apparatus is expressed as tracheobronchial deposits in diffuse plaques that can cause stenosis or parenchymal nodules or masses. In this regard, we report four cases of pulmonary amyloidosis and discuss the diagnostic difficulties of this location. These are two women and two men aged 60, 68, 44 and 57 years. They presented a pulmonary parenchymal amyloidosis in all cases associated with bronchial in one case. The diagnosis was confirmed by histology in all cases. The staging was negative in all cases. The evolution was marked by the stabilization of the lesions in all cases. Localized amyloidosis, which may be the only telltale sign of a systemic illness, its diagnosis requires finding other locations to better tailor the treatment strategy.
