Fluorescence in situ hybridization (FISH) analysis was done in some of the studies before, which revealed FUS/EWSR1-DDIT3 fusion to be negative and also the absence of MDM2 amplification in this type, which differentiates MPLPS from the conventional myxoid liposarcoma [7,9]. The gene discussed is EWSR1; the disease is myxoid liposarcoma.
