Benign edematous polysynovitis in the elderly (RS3PE syndrome)

The Authors provide an update on benign edematous polysynovitis in the elderly and propose clinical and laboratory criteria for a correct diagnosis. They also propose the use of the term "polysynovitis" rather than polyarthritis, as they think it describes the histopathological findings of the disease better. Finally, they attempt to correctly distinguish RS3PE syndrome from polymyalgia rheumatica, rheumatoid arthritis and chondrocalcinosis.
