Synovial Sarcoma

Synovial sarcoma is a cancerous soft tissue tumor that usually occurs near the joints. Under the microscope a synovial tumor resembles synovial tissue (the lining tissue of joints). This tissue is found around the tendons (bands of fiber that connect muscle to bone) and can form bursa (fluid filled cushioning pouches or sacs found in spaces between tendons, ligaments, and bones).

  • Synovial sarcoma tends to occur in adolescents and young adults and affects more males than females.
  • The most common location is the thigh near the knee, but synovial sarcoma can also occur near other joints, mainly in the arms and legs. It seldom arises within a joint.
  • Synovial sarcoma can spread (metastasize) to other areas of the body, particularly to involve regional lymph nodes.
