CME-Rheuma 21: Precision Medicine - Synovial Biopsy in Rheumatology Abstract. Synovial biopsy is increasingly performed in the medicine of the musculoskeletal system. On the one hand it allows the in-depth diagnosis of unclear arthritides. On the other hand, there is an increasing body of publications showing that histology, immunohistochemistry and RNA analysis of synovial tissue may lead to subclassifications within rheumatoid arthritis. This in turn may have predictive value for the treatment response. We herein give a short overview of the joint biopsy technique, the basic evaluation of biopsy samples and the prospects of synovial biopsy.
