Outcomes and Complications of Corticosteroid Injection of Rheumatoid Nodules.

For short-term symptomatic relief, smaller RN can be safely injected with triamcinolone. Large symptomatic RN (≥2cm) are at greater risk of infection; thus, in these cases, lower corticosteroid doses or surgical excision may be preferred. In the long-term, effective systemic antirheumatic therapy with treat-to-target is the best approach.
