Kaplan syndrome

Caplan syndrome is also known as rheumatoid pneumoconiosis, rheumatoid arthritis-pneumoconiosis, and silicosis arthritis. In 1953, Caplan in the United Kingdom discovered that pneumoconiosis coal miners with rheumatoid arthritis may have specific lung shadows. Later the disease was called Kaplan syndrome. Later, it has been confirmed that inhalation of other inorganic dusts such as free silicic acid, silicate, iron, aluminum can also cause this syndrome. At present, those with silicosis combined with rheumatoid arthritis and characteristic shadows in the lungs are called Kaplan syndrome.
