With respect to soft tissue tumor type, concordant cases included all eight Ewing sarcomas (four with EWSR1‐FLI1, three with EWSR1‐ERG, and one with EWSR1‐FEV), all eight synovial sarcomas with SS18‐SSX1/2, all seven myxoid liposarcomas with FUS/EWSR1‐DDIT, and all three desmoplastic small round cell tumors (DSRCT) with EWSR1‐WT1. Here, SS18 is linked to synovial sarcoma.
