Paraneoplastic remitting seronegative symmetrical synovitis with pitting edema (RS3PE), improved following surgical resection of prostatic carcinoma: A case report.

RS3PE syndrome is a rare condition that occurs in elderly individuals which can present alone or in association with various rheumatic or malignant diseases. We present a case of a 77-year-old man who was diagnosed with adenocarcinoma of the prostate and initially under active surveillance. 2 months after the diagnosis, he presented with arthralgia in both shoulders and knees, pitting edema of the both hands and feet. The patient underwent radical prostatectomy since the link between prostatic carcinoma and RS3PE was suspected. After 7 months from operation, the patient has no symptoms or signs of RS3PE.
