[Multiple intrapulmonary rheumatoid nodules].
A 66-year-old woman who had been treated at a nearby hospital since 1977 for rheumatoid arthritis complained of cough. Chest X-ray films disclosed multiple nodular shadows with cavitation in the fields of both lungs. The patient was admitted to our hospital and a thoracoscopic lung biopsy was performed. Histologically, the nodule consisted of necrotizing granuloma, indicating a necrobiotic nodule. Rheumatoid nodule was diagnosed because the patient exhibited rheumatoid arthritis. The chest X-ray shadow disappeared without medication. Rheumatoid nodules without coniosis are uncommon, but should be considered in the differential diagnosis of lung nodular lesions in patients with rheumatoid arthritis.
