Synovial sarcomas account for up to 10% of soft-tissue sarcomas, typically arising in the para-articular regions in adolescent and young adults1.

A characteristic SYT(SS18)-SSX fusion gene resulting from the chromosomal translocation t(X;18)(p11;q11.2) is detectable in more than 90% of synovial sarcomas2, suggesting this is the primary causal event. The translocation fuses the SYT gene from chromosome 18q11.2 to either of two highly homologous genes at Xp11: SSX1 (Synovial Sarcoma X Breakpoint 1) or SSX2. In less than 1% of cases, SYT will be fused to a third gene, SSX43. SYT-SSX1 and SYT-SSX2 are thought to disrupt transcription and the subsequent expression of specific target genes4,5.
