Remitting seronegative symmetrical synovitis with pitting edema syndrome in maintenance hemodialysis

Introduction The remitting seronegative symmetrical synovitis with pitting edema syndrome primarily occurs in elderly individuals to represent symptoms of edema, pain, and joint swelling. It could be misdiagnosed in elderly maintenance hemodialysis patients, as hemodialysis patients often present with pain and joint swelling induced by hypervolemia, inflammation, amyloidosis, and/or chronic kidney disease. Here, we describe a maintenance hemodialysis patient with remitting seronegative symmetrical synovitis with pitting edema syndrome. Case presentation A 71-year-old man on maintenance hemodialysis who complained of continuous pain and swelling of joints was diagnosed with remitting seronegative symmetrical synovitis with pitting edema syndrome on his clinical findings that revealed tenosynovitis at the joint without joint erosions and no elevation of anti-cyclic citrullinated peptide antibody and rheumatoid factor. After administration of prednisolone, systemic edema, and pain improved in 2 days. Conclusion Remitting seronegative symmetrical synovitis with pitting edema syndrome should be considered as a differential diagnosis in hemodialysis patients with edema and/or arthralgia.
