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]
- Pleural plaques.
- Asbestosis.
- Lung carcinoma.
- Malignant mesothelioma.
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]
- Interstitial fibrosis - similar to usual interstitial pneumonia (UIP).
- Ferruginous bodies - key feature.
- Segmented twirling baton with long slender fibre within.
