Remitting, seronegative (A) symmetrical synovitis with pitting edema--two cases of RS3PE syndrome

Abstract

The sparing effect of neurological damage on the development and progression of several arthritic conditions has been documented. We describe the first 2 cases of unilateral remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome in individuals with neurologic disorders. Case 1 suffered from birth trauma resulting in paresis of the right upper extremity and developed RS3PE syndrome in the nonaffected extremities. Case 2 developed RS3PE syndrome on the nonparetic side 7 years after a cerebrovascular accident resulting in hemiparesis.
