Pneumoconiosis

Overview
Pneumoconiosis is an occupational lung disease caused by the inhalation of dust. Depending on the type of dust, variants of the disease are considered.

Types include:
 * Coalworker's pneumoconiosis (also known as "black lung") - coa] dust
 * Asbestosis - asbestos dust
 * Silicosis (also known as "grinhelloders' disease") - silica dust
 * Bauxite fibrosis - bauxite dust
 * Berylliosis - beryllium dust
 * Siderosis - iron dust
 * Labrador Lung (found in miners in Labrador, Canada) - mixed dust, including iron, silica and anthophyllite, a type of asbestos

Pneumoconiosis in combination with multiple pulmonary rheumatoid nodules in rheumatoid arthritis patients is known as Caplan's syndrome.
