To the generic group of the gliomas belong the tumors designated astrocytomas, and, according to Ewing,* these neoplasias are, in general, cerebral or cerebellar tumors of slow growth, composed principally of adult glial cells. The astrocytomas have a special structure and are relatively acellular and scarcely vascularized. Microscopically, they are observed to be composed of stellar cells, between which can be seen fine cytoplasmic fibers; in some cases these fibers are scarce or nonexistent. Bailey and Cushing named them "protoplasmic astrocytomas," and, according to them, they have a greater activity than the fibrillated forms. These authors make no mention of astrocytomas other than those localized in tissue of the cerebrospinal axis.

On the other hand, localization of tumoral formations of neural tissue outside of the cerebral or cerebellar axis does occur, although rather infrequently, and the finding of such neural tissue in the nose deserves, in all cases, to be
