[Localised bronchi amyloidosis: a case report]. / Amylose bronchique localisée: une observation.

ABSTRACT

Localised pulmonary amyloïdosis is exceptional. Tracheobronchial symptoms are the most frequent. We report a case of a 68 year-old man complaining of cough and breathlessness. Bronchoscopy showed a submucosal infiltration with stenosis of left upper and lower bronchi. Multiples biopsy were performed and concluded to amyloïdosis of AL type. Our objective is to describe the anatomopathologic aspects of localised pulmonary amyloïdosis and to discuss its pathogeny.
