Figure 1: Photomicrograph showing ribbons of primitive neuroepithelium (above left, arrow) mimicking embryonic neural tube; in other areas of the tumor, sheets of undifferentiated neuroectodermal cells (lower right, thin arrow) with interspersed ependymoblastic rosettes (arrow head) (H & E stain, 40× magnification). (Inset, below right) Sheets of undifferentiated neuroectodermal cells at higher magnification (H & E stain, 400× magnification). (Inset, above right) Characteristic multilayered ependymoblastic rosette, with outer cell layer merging with the undifferentiated cells (H & E stain, 400×)
