Asbestosis is diffuse lung disease due to asbestos exposure.

General

Definition:

  • Interstitial lung disease due to asbestos exposure.[1]
    • Important to diagnose... asbestosis = compensation.

Conditions associated with asbestos exposure (mnemonic PALM):[1]

Possible association with asbestos exposure:

Diagnosis:

  • Rests on morphology with special techniques (e.g. polarization)[3] and includes tunneling electron microscopy (TEM),[4] as done at special centres.
    • Tissue is typically digested prior to fibre counting.[5]

Microscopic

Features:[5]

  1. Interstitial fibrosis - similar to usual interstitial pneumonia (UIP).
  2. Ferruginous bodies - key feature.
    • Segmented twirling baton with long slender fibre within.
