Complete disappearance of pulmonary rheumatoid nodules after long term rituximab treatment: case report

The natural history of pulmonary rheumatoid nodules in rheumatoid arthritis remains uncertain. We present a case of a patient with rheumatoid arthritis with pulmonary rheumatoid nodules diagnosed while receiving etanercept in whom pulmonary nodules resolved completely after 5 years of rituximab treatment. Rituximab has been evaluated in case series of patients with pulmonary rheumatoid nodules, resulting in most cases in no progression or a reduction in the size of the nodules, although the complete resolution is uncommon probably due to the short follow-up period. Complete disappearance of pulmonary rheumatoid nodules may be expected after long-term treatment with rituximab.
