  • Categorized by clinical syndrome (systemic or localized) and biochemical type
  • Currently 25 distinct types of amyloid fibers
  • Four major types are AL protein (amyloid light chain), AA protein (amyloid associated), ATTR protein (transthyretin, formerly prealbumin) and B2-microglobulin

In lung, four major clinical syndromes:
  • Systemic (generalized) pulmonary amyloid
  • Localized pulmonary amyloid (tracheobronchial and nodular forms)
  • Diffuse interstitial septal amyloidosis (diffuse parenchymal amyloid, interstitial, septal or vascular amyloid)
  • Pleural amyloid (very rare)
