[Diffuse pulmonary amylosis. Apropos of 2 cases associated with Waldenstrom's disease].

Diffuse pulmonary amyloidosis is rarely reported in systemic amyloidosis. We report two patients with Waldenström's macroglobulinemia in whom pulmonary amyloidosis was revealed by a diffuse interstitial syndrome without severe functional impairment. Amyloid pulmonary deposits are anatomically frequent and are often associated with cardiac amyloidosis. They must be evoked more frequently in the diagnosis of diffuse interstitial patterns, particularly in patients with primary amyloidosis or dysglobulinemia.
