Histopathological features of ependymal differentiation in the embryonal‐appearing components of ELTMDs include a dot‐like pattern of cytoplasmic EMA positivity and small to large tubular structures with linear EMA positivity along the apical surface resembling ependymal rosettes and tubules, which are histological characteristics of ependymoma (Figures 2E and 3D). This evidence concerns the gene MUC1 and ependymoma.
