AbstractRemitting seronegative symmetrical synovitis with pitting edema is a rare but well-recognized clinical entity that is easily overlooked due to lack of clinical vigilance. It is classically described as an acute onset of symmetrical tenosynovitis of both upper and lower extremities with pitting edema, mostly noted in elderly population. Young patients with other rheumatological diseases and unilateral involvement had also been reported, but symmetrical remitting seronegative symmetrical synovitis with pitting edema in a young patient is a rare observation. We hereby report a case of a remitting seronegative symmetrical synovitis with pitting edema in a young male affected by no rheumatological diseases in the past, typically fulfilling the diagnostic criteria and well responded to low-dose steroid therapy. The salient features of the present case in terms of age, remitting seronegative symmetrical synovitis with pitting edema possibly related to undifferentiated arthropathy, reactive arthritis, or diabetes mellitus.© The Author(s) 2020.
