How is synovial sarcoma diagnosed?

A doctor may use the following procedures and tests to diagnose synovial sarcoma:[1]
  • Biopsy: Tissue is removed for examination under a microscope.
  • Immunohistochemical analysis: Tumor tissue is tested for certain antigen and antibody interactions common to synovial sarcoma.
  • Ultrastructural findings: The tissue is examined using an ultramicroscope and electron microscope.
  • Genetic testing: Tissue is tested for a specific chromosome abnormality common to synovial sarcoma. The characteristic chromosome translocation t(X;18)(p11.2;q11.2) is present in nearly all synovial sarcomas, providing strong evidence for the diagnosis of this tumor.[2]
