rheumatic nodule

Rheumatic nodules refer to subcutaneous nodules appearing in certain parts of rheumatoid arthritis patients. The formation mechanism, common parts, clinical significance, appearance characteristics, diagnostic value and treatment are as follows: 1. The formation mechanism of rheumatic nodules is mainly due to the deposition of immune complexes and inflammatory reactions. When rheumatoid arthritis is active, immune abnormalities prompt it to form nodules around joints and other parts. 2. Common parts often appear on the extension side of joints, such as elbows, dorsal joints, etc., but also in other parts such as Achilles tendon. 3. Clinical significance Its appearance often indicates that rheumatoid arthritis may be active or in progress, but not all patients will appear. 4. Appearance characteristics are usually round or oval, hard, movable subcutaneous nodules, varying in size. 5. Diagnostic value for the diagnosis of rheumatoid arthritis has certain auxiliary significance, but can not rely solely on rheumatic nodules to diagnose. 6. Treatment With the effective control and remission of rheumatoid arthritis, rheumatic nodules may gradually shrink or even disappear. Treatment is mainly aimed at rheumatoid arthritis itself, including the use of immunosuppressants, such as methotrexate, leflunomide, etc. Rheumatic nodule is a characteristic manifestation of rheumatoid arthritis, which has certain reference value for evaluating the condition and guiding the treatment.
