title: [Are the medulloepithelioma, ependymoblastoma and embryonal tumor with multilayered rosettes the same entity?].
abstract: Medulloepithelioma is a rare malignant tumor arising in cerebral hemispheres. Microscopically, medulloepithelioma is characterized by epithelial structures that mimic the embryonic neural tube. Immunohistochemical analysis revealed that tumor cells are immunopositive for LIN28A and fluorescence in situ hybridization showed an amplification of a miRNA cluster at 19q13.42. Presence of these both aberrations suggesting that medulloepithelioma, ependymoblastoma and embryonal tumor with multilayered rosettes are the same entity.
