Symptoms of a synovial sarcoma include a tender lump or swelling at the affected site, numbness or pain and a limited motion range, according to the University of Rochester Medical Center. Synovial sarcoma is a slow-growing tumor and may not initially present with symptoms, which results in delayed diagnoses.
The University of Rochester Medical Center notes that synovial sarcoma symptoms are sometimes mistaken for bursae, synovial tissue or joint inflammation. Diagnosing the condition is done via a biopsy, immunohistochemical analysis, ultrastructural findings or genetic testing. In an immunohistochemical procedure, antibody and antigen interactions are tested on the tumor tissue. In the ultrastructural findings procedure, an electron microscope or ultramicroscope is used to examine the tumor tissue.
Treatment for synovial sarcoma depends on factors such as the tumor location, grade and size, as well as the patient's age and the extent of the disease, explains the University of Rochester Medical Center. Surgery to excise the whole tumor is the most common treatment method for synovial sarcoma. The doctor may perform a second surgery if the entire tumor is not removed. Before and after surgery, the patient may also receive radiation therapy to decrease the chance that the cancer returns and to control the tumor size.
