title: [Ultrastructural analysis of ependymoastrocytoma histogenesis].
abstract: Electron-microscopy of tumours, diagnosed by light optics as ependymoastrocytomas, helped to ascertain the common features in the ultrastructural organization of their tumorous tissue: a complex of organ-specific signs of ependymomas is constantly manifested in all the scrutinized parts of the tumorous nodes. This makes it possible to regard ependymoastrocytomas as a variant of ependymomas and not tumours of a mixed origin.
