Synovial sarcoma (SS) is a rare subtype of soft tissue sarcoma with a median age at diagnosis between 35 and 38 years.1,2 SS can arise anywhere in the body and most commonly presents in the extremities.2 The tumor is defined by the presence of a translocation t(X,18), which results in an aberrant SS18:SSX fusion protein that promotes tumorigenesis.2 This evidence concerns the gene SS18 and synovial sarcoma.
