title: [Embryonal neuroepithelial tumors of the cerebral hemispheres].
abstract: 33 embryonal neuroepithelial tumours of the cerebral hemispheres were examined light- and electron-microscopically, immunohistochemically. 4 types of tumours were distinguished: neuroblastoma, neuroepithelioma, ependymoblastoma and choroid carcinoma. Each type was characterised by its own pathohistological, immunohistochemical and ultrastructural features. Our results and literature data prove immunophenotypic and ultrastructural heterogeneity of embryonal neuroepithelial tumors of the cerebral hemispheres, in spite of some similarities in their pathohistological features.
