  • Abstract
  • Look Inside

The cellular density (the number of the cells seen in a microscopical sight-field under magnification of × 600) has been calculated in different gliomas of the brain, comprising 75 cases. The means and the confidence-intervals of the cellular density are shown in the follo-wing: Astrocytoma 152 (164—352); Glioblastoma 408 (464—352) in Araki's Series and 458 (503—413) in Busch's Series; Ependymoma (cellu-lar) 394 (460—329); Pinealoma 298 (354—242); Medulloblastoma 676 (724—628); and Oligodendroglioma 297 (361—233).

Provided that the cellular density of more than 400, between 200 and 400, and less than 200 be defined to be called "very cellular," "moderately cellular," and "relatively acellu-lar," respectively, it can be said that glioblas-toma and medulloblastoma are "very cellular" tumors, and astrocytoma is a "relatively acellu-lar" tumor. Gliomas other than these three types should be considered as "moderately cellular" tumors, to which oligodendroglioma also belongs.

From the viewpoint of the cellular density, the so-called transitional glioma ranks between the "relatively acellular" astrocytoma and the "very cellular" glioblastoma.

When the cellular density only is taken into consideration, gemi tocytoma, astroblastoma and polar spongioblastoma may likewise be cl-assified as transitional glioma.
