These are typically present as asymptomatic, firm, fixed, or mobile subcutaneous nodules adjacent to bony structures. The most common site is the elbow (Fig. 13-8). Other common locations include the extensor aspects of the fingers, flexor sheath tendons in the palms, Achilles tendons, ischial tuberosities, and sacrum. Rheumatoid nodules occur in approximately 25% of patients with rheumatoid arthritis.
