Paraneoplastic Syndrome in Double Cancer (Renal Cell Carcinoma and Colon Cancer) Presenting with Polymyalgia Rheumatic: A Case Report / 日本プライマリ・ケア連合学会誌

ABSTRACT

A 68-year-old man underwent surgery for renal cell carcinoma half a year ago, and developed low back and hip pain. The pain did not respond to antibiotics. Collagen disease, in particular ankylosing spondylitis, was suspected and steroids were administered, resulting in the improvement of the symptoms. polymyalgia rheumatica (PMR) was diagnosed.As all symptoms improved following resection of the metastatic lymph nodes, he was diagnosed with paraneoplastic syndrome. A biological preparation (pazopanib) was administered for renal cell carcinoma, but colon cancer was diagnosed, followed by extirpation of the colon tumor. Although the patient had recurrent thigh pain, he was able to leave the hospital temporarily with walking aids.This is the first report of PMR as paraneoplastic syndrome after surgery for renal cell carcinoma in a patient with colon cancer.
