Abstract:
The hitherto conventional classification of primitive brain tumours has been recently, and somewhat tentatively, revised for pediatric pathology: a new class of tumours, named Primitive Neuroectodermal Tumours (PNET) has been established, encompassing many undifferentiated, small cell tumours of uncertain origin, mainly medulloblastomas. This paper deals with these concepts, and with some practical and/or theoretical problems mainly concerning childhood lobrastrocytomas, medulloblastomas and ependymomas, regarding the role of pathology in their diagnosis and prognosis.
