NCOA1 and anaplastic ependymoma: The tumors collected for this study displayed a mixed histology, and one of the major components demonstrated embryonal‐appearing histology (Figure 2B–D), being the most similar to anaplastic ependymoma considering the minimal ependymal differentiation observed in the components and the detected fusion genes, C11orf95‐NCOA1/2 or ‐RELA.
