The hallmark genomic alteration in SS is t(X;18;p11;q11), resulting in the formation of an oncogenic fusion gene, usually SS18(SYT):: SSX1 or SS18::SSX2 and rarely SS18::SSX4. We herein describe a case of an epithelial-predominant SS arising in the right inguinal soft tissue of a 62-year-old woman. Here, SSX4 is linked to synovial sarcoma.
