Organ limited amyloidosis with lymphadenopathy

Abstract

Hilar and mediastinal lymphadenopathy associated with localized pulmonary amyloid is very rare. We describe two cases of this unusual combination, one of endobronchial amyloid with adenopathy and the other of nodular parenchymal amyloid with hilar nodes. In both these cases the nodes contained calcification, and in the nodular parenchymal case in particular, this appearance is highly suggestive of pulmonary amyloid.
