EWSR1 and neoplasm: As tumors with partial morphological and immunohistochemical overlapping with EWS do exist and have been grouped under the name of “Ewing-like sarcomas” [42], including CIC-rearranged sarcoma, sarcoma with BCOR genetic alterations and round cell sarcoma with EWSR1-non-ETS fusions, we suggest that any neoplasms with EWS morphology should be tested by molecular analyses for confirming the diagnosis.
