Other asbestos-related pleural disease:<ref name=pmid22617814/>
*Diffuse pleural thickening.
*Benign asbestos-related pleural effusions (BAPEs).
*[[Malignant mesothelioma]].

*Thickened (or calcified) plaques.<ref name=pmid17867573/>

==Microscopic==
Features:<ref name=pmid5556121/>
*Hyaline material +/- [[calcification]].
 
Notes:
*Usually associated with asbestosis fibres in the [[lung]] (85% of cases).<ref name=pmid5556121>{{Cite journal  | last1 = Roberts | first1 = GH. | title = The pathology of parietal pleural plaques. | journal = J Clin Pathol | volume = 24 | issue = 4 | pages = 348-53 | month = May | year = 1971 | doi =  | PMID = 5556121 }}</ref>
**Plaque burden seems to be associated with the number asbestos bodies found; many plaques... suggest many asbestosis bodies.

*[[Desmoplastic mesothelioma]].
