Asbestosis

(Science: chest medicine) fibrosis of the lung as a result of the chronic inhalation of asbestos fibres.

The needle like asbestos fibres are phagocytosed by alveolar macrophages but burst the phagosome (phagocytic vesicle) and kill the macrophage and the cycle is repeated.

Mesothelioma, a rare tumour of the mesothelial lining of the pleura, is associated with intense chronic exposure to asbestos dust, particularly that of crocidolite asbestos.
