ABSTRACT
Rheumatoid arthritis is a painful disfiguring condition usually affecting the hands and feet as well as larger joints such as the knees. Lung complications are relatively unusual but may include: • pleurisy and pleural effusion; • bronchiolitis obliterans; • bronchiectasis; • pulmonary fibrosis; • rheumatoid nodules (which may be multiple). These may provide a
difficulty in diagnosis from lung cancer; • Caplan’s syndrome in coal workers with pneumoconiosis. Large nodules
which may cavitate.
