Embryonal tumors with multilayered rosettes (ETMRs) which otherwise lack rosettes, a medulloepithelioma component, and neurocytic/neuropil-rich areas could also resemble embryonal tumors with BRD4::LEUTX fusions, but they are generally negative for OLIG2 and positive for LIN28A. This evidence concerns the gene OLIG2 and embryonal neoplasm.
