Abstracts

The histological study of four cases and one by electron microscopy of subependyomomas allowed us to obtain morphostructural characteristics of ependymocytes and astrocytes. Comparing these findings to those of the present day literature, we propose to name these tumours ependymal astrocytomas.

O estudo histológico de quatro casos de subependimoma, um deles pela microscopia eletrônica, permitiu-nos obter características morfoestruturais de ependimócitos e astrócitos. Comparando estes achados com os da literatura, propomos denominar tais neoplasias como ependimoastrocitomas.
