What is Synovial Sarcoma?

  • Synovial sarcoma is a rare, malignant tumor of the soft tissues, usually around joints. Under the microscope the tumor resembles synovial tissue, which is found around the tendons (bands of fiber that connect muscle to bone). 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.
