Amyloidosis is a heterogeneous group of diseases characterized by the extracellular deposition of misfolded proteins that can affect either systemically or locally confined to one system. Pulmonary amyloidosis is rare and can be classified into three forms according to the anatomic site of involvement: nodular pulmonary amyloidosis, tracheobronchial amyloidosis and diffuse alveolar-septal amyloidosis. The former two usually represent localized amyloid disease and the latter represents systemic disease. Typically lung parenchymal and tracheobronchial amyloidosis do not present together in localized forms of pulmonary amyloidosis. Here we report a unique case of localized pulmonary immunoglobulin light-chain amyloidosis, manifested as both parenchymal nodules and tracheobronchial amyloid deposition.
INTRODUCTION Amyloid are insoluble heterogenous proteins predominantly composed of [beta]-sheet structure that characteristically bind to the dye Congo Red and produce an apple-green birefringence under polarized light microscopy [1]. With [...]
