Classification and Nosography of Neuroepithelial Tumors

Abstract

A century has now elapsed since the first attempts to classify cerebral neoplasms systematically. The identification of new cellular elements in the nervous tissue, their histogenetic classification, the discovery of other morphological tumor features and the accruing of biological data have progressively led to the classifications being updated. This has been facilitated by the progress in neurosurgery and, more recently, by the introduction of molecular biology into neuro-oncology.
