All of the following features are seen in asbestosis except -
Asbestosis 

There are two distinct geometric forms of asbestos -



Serpentine chrysotile


Amphibole (crocidolite)



Serpentine chrysotile accounts for most of the asbestos used in industry.
Both serpentine and amphibole can cause all asbestosis related disease except for mesothelioma, which is usually associated with amphibole (crocidolite).

Asbestos-related diseases 

Localized fibrous plaques which may be calcified.
Diffuse pleural fibrosis
Pleural effusion
Parenchymal interstitial fibrosis (asbestosis).
Lung carcinoma → Most common neoplasm associated with asbestos exposure.
Mesothelioma of pleura and peritoneum most specific neoplasm associated with asbestos exposure.
Laryngeal and colon carcinomas.
Stomach carcinoma

Note: - Concomitant cigarette smoking greatly increases the risk of lung carcinoma but not that of mesothelioma.
Diffuse pulmonary interstitial fibrosis.
Fibrous pleural thickening.
Emphysema
Calcified pleural plaques
