The antiquity of rheumatoid arthritis (RA) is still in dispute, due to the difficulty of conclusively differentiating peripheral polyarthritis, especially from spondyloarthropathy, in archaeological populations. In view of the importance of genetic factors in developing spondyloarthropathy and of the far lower prevalence of the disease in modern Japanese, a rarity of peripheral polyarthritis would be anticipated in the ancient Japanese population, given that RA had not been present there. One hundred and sixty adult Japanese skeletons of the late and final Jomon period (3400–2400 years bp ) were examined to find peripheral polyarthritis. There was one male skeleton with peripheral polyarthritis, showing marginal and surface erosions in the joints of the hands, feet, ankle and zygoapopheseal joints of the thoracic vertebrae. RA is suggested as the most probable cause of this pathology. This report raises the significance of further studies to consider whether more cases than anticipated exist in skeletal populations that would have been resistant to developing spondyloarthropathy.
