EWSR1 is the most commonly rearranged gene in mesenchymal neoplasia, and its myriad chimeric oncoproteins drive widely disparate neoplasms. Here, we survey selected EWSR1 rearrangements, including well-described EWSR1 fusions with CREB family members, ATF1 and CREB1, as well as fusions in emerging entities such as mesenchymal neoplasms with EWSR1::PATZ1 and EWSR1::NFATC2 fusions. We also discuss recent data demonstrating the imperfect specificity of EWSR1::WT1 and, possibly, EWSR1::FLI1 fusions. © Author(s) (or their employer(s)) 2024. No commercial re-use.
