Pneumoconiosis is an occupational lung disease and a restrictive lung disease caused by the inhalation of dust.

Types

Depending on the type of dust, variants of the disease are considered.

Types include:

• Anthracosis - carbon dust
• Coalworker's pneumoconiosis (also known as "black lung") - coal dust
• Asbestosis - asbestos dust
• Silicosis (also known as "grinder's disease") - silica dust
• Bauxite fibrosis - bauxite dust
• Berylliosis - beryllium dust
• Siderosis - iron dust
• Byssinosis - cotton dust
• Silicosiderosis - mixed dust containing silica and iron
• Labrador Lung (found in miners in Labrador, Canada) - mixed dust containing iron, silica and anthophyllite, a type of asbestos

Positive indications on patient assessment:

• Shortness of breath
• Chest X-ray may show a characteristic patchy, subpleural, bibasilar interstitial infiltrates or small cystic radiolucencies called honeycombing

Pneumoconiosis in combination with multiple pulmonary rheumatoid nodules in rheumatoid arthritis patients is known as Caplan's syndrome.^[1]
