Comparative histopathological analysis between tenosynovitis and joint synovitis in rheumatoid arthritis

Abstract

The histopathological features of RA tenosynovitis were indistinguishable from those of joint synovitis. Therefore, it is suggested that the ongoing inflammation is driven by similar mechanisms in the tenosynovium and joint synovium and that RA is probably a tissue-specific disease which targets systemic synovial tissues.
