Description

Polymyalgia rheumatica (PMR) was a rare rheumatic disease in Japan, nevertherless common in European and American caucasians. In Japan recently PMR is one of well established rheumatic diseases. We experienced four cases of PMR in our rheumatic clinic for the past five years. Only one of them was male and the youngest case was 41 years of age. Most of them presented with myalgic pains of proximal areas of trunks, continuous fever and emaciation. It took for long time (3 months to 4 years) inorder to diagnose PMR. The previous diagnosis were fever of unknown origin (FUO) or some collagen diseases. One of them was a case associated with temporal arteritis, which was diagnosed from a biopsy finding of temporal artery. Other case was strongly suspected to be associated with temporal arteritis. All of them well responded to corticosteroid administration, and myalgic pain and fever episodes disappered promptly. It was difficult to taper off the corticosteroid in all cases. In serological examination it was showed that one of them had the antibody against DNA.
