A 30-year-old woman with SLE has ulnar deviation and swan neck deformities of both hands. Radiographs show reducible deformities with no erosions and preserved joint spaces. What is this entity called?
- A Rheumatoid arthritis with radiographic remission
- B Jaccoud arthropathy ✓
- C Ehlers-Danlos syndrome
- D Rhupus syndrome
Correct answer: B. Jaccoud arthropathy
Explanation
Jaccoud arthropathy is a non-erosive, reversible deforming arthropathy of SLE caused by capsular and ligamentous laxity from chronic synovitis, producing ulnar deviation and swan neck deformities that can be corrected on examination. Erosive, fixed deformity would indicate true rheumatoid disease. Rhupus denotes coexistence of genuine RA and SLE with erosions, which contradicts the film shown here.
