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.

  • Our pediatric oncologists have access to, and often lead, some of the most innovative clinical trials for soft tissue sarcomas.
  • Our surgeons have specialized expertise in complex surgeries, and our radiation oncologists have access to the newest radiation therapy techniques that may also be used in the care of a child with soft tissue sarcoma
