[edit] Discussion of Pulmonary amyloidosis

  • Amyloidosis limited to the respiratory tract is uncommon.
  • Pulmonary amyloidosis occurs in three histopathologic types
    • Focal deposits in the tracheobronchial tree
    • Diffuse parenchymal opacities
    • Single or multiple pulmonary nodules.
  • Nodular pulmonary amyloidosis is usually found incidentally on chest nadiognaphs in asymptomatic, older adults.
  • The deposits originate in the muscular walls of small blood vessels, and as they enlarge, they spread into the interstitial tissues.
