ARTICLE HIGHLIGHTS
Case characteristics

A 71-year-old woman was referred to our hospital with finger stiffness; edema of both hands and feet; and bilateral pain in the shoulder, wrist, metacarpophalangeal, proximal interphalangeal, and ankle joints.

Clinical diagnosis

Physical examination showed remarkable pitting edema in the dorsum of the hands and feet, as well as bilateral tenderness and swelling in the shoulder, wrist, finger, and ankle joints.

Differential diagnosis

Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome and rheumatoid arthritis were considered.

Laboratory diagnosis

Blood test results were as follows: WBC, 5100/μL (neutrophils, 75%); CRP, 20.8 mg/dL; erythrocyte sedimentation rate, 99 mm/h; RF, negative; matrix metalloproteinase 3 (MMP-3) 488 ng/mL; VEGF, 135 pg/mL; HLA-B 7, (+).

Treatment

Treatment with prednisolone (15 mg/d) was started.

Experiences and lessons

We report a patient with RS3PE syndrome and elevation of MMP-3. MMP-3 was more indicative of RS3PE syndrome symptoms than was CRP.
