Rheumatoid arthritis is a systemic disease of unknown cause and autoimune disease mechanisms. Its main clinical feature is a chronic polyarthritis involving large and small joints that may cause deformities and disabilities. Subcutaneous nodules can be part of the clinical presentation with a typical pathological appearance. Visceral involvement may include lungs, pericardium, and blood vessels. Pulmonary involvement is characterized by pleural effusions, vasculitis, bronchiolitis and pulmonary rheumatoid nodules. Usually, visceral manifestations appear after arthritis development. Pulmonary rheumatoid nodules are a rare feature. Its development preceding arthritis make this characteristic even more interesting. Our case report refers to a female patient with pulmonary rheumatoid nodules that has preceded the arthritis.
