Pneumoconiosis refers to a class of occupational restrictive lung diseases characterized by pulmonary fibrosis resulting from the inhalation and deposition of specific mineral or organic particulate matter, such as quartz silica in silicosis, carbon particles in coal workers' pneumoconiosis, and amphibole serpentine fibers in asbestosis. These conditions fundamentally alter alveolar compliance through scar formation, leading to impaired inspiratory lung expansion; the nature of the causative agent further dictates specific pathological sequelae including calcified hilar lymph nodes in silicosis, rheumatoid arthritis association in coal workers' pneumoconiosis (Caplan syndrome), and pleural plaques or mesothelioma in asbestosis.
