title: Microglioma and/or reticulosarcoma of the nervous system.
abstract: 49 microgliomas of nervous parenchyma were studied, all of them with aniline techniques in part of the material embedded in paraffin, and the rest with Del Rio Hortega-Polak's technique in frozen sections. It is considered that the microglia is the representative of the R.E.S. in the nervous tissue, and is characterised by its cytoplasmic argentophilia. The existence of a non-argentophilic primitive reticular cell is denied, and it is maintained that microglioma and reticulosarcoma are synonymous thus refuting the concept of the existence of a reticulosarcoma consisting of non-argentophilic cells and a microglioma consisting of argentophilic cells, as different neoplasms.
