Remitting seronegative symmetrical synovitis with pitting edema associated with gastric carcinoma

We report a case of remitting seronegative symmetrical synovitis with pitting edema (RS3PE syndrome) associated with gastric carcinoma in an 80-year-old woman who developed polyarthritis with marked pitting edema of the dorsa of both hands and feet 7 days after fiberscopic examination of the stomach. A mass lesion was identified and histology of the biopsy specimen revealed gastric carcinoma. Polyarthritis and edema were partially relieved by an intraarticular injection of corticosteroid. Shortly after resection of the gastric carcinoma, her symptoms and signs disappeared. She has been free of symptoms for 3 yrs without medication.
