title: The syndrome of seronegative symmetrical synovitis with pitting edema (RS3 PE syndrome): a unique form of arthritis in the elderly? Report of 4 additional cases.
abstract: We describe 4 elderly patients who presented with peripheral seronegative inflammatory polyarthritis with pitting edema. All of these patients had a spontaneous benign evolution of their disease within 9 to 18 months. None developed erosions or relapse after prolonged followup. This particular pattern of arthritis in elderly patients might represent a separate benign clinical entity among inflammatory arthritis in aging patients.
