Three Cases of Polymyalgia Rheumatica

Although increasing number of cases has been reported, polymyalgia rheumatica (PMR) is still a rare disease in Japan. We report three cases of PMR. Three patients were diagnosed as typical PMR. They had noted aching and stiffness in the shoulder and thigh with fever. In blood examination, inflammatory sign was very remarkable, but serum rheumatoid factor was negative. All arthritic conditions disappeared quickly after steroid therapy and the improvement of the inflammatory sign and myalgia was observed.
