WebReactive gliosis Gliosis is a common parenchymal reaction in the CNS and, although indicative of a pathological process, it is entirely nonspecific. Fibrillary and especially gemistocytic gliosis may at times be difficult to distinguish from a low-grade infiltrating astrocytoma, especially in smears or small biopsies.

Gliosis is a nonspecific reactive change of glial cells in response to damage to the central nervous system (CNS). In most cases, gliosis involves the proliferation or hypertrophy of several different types of glial cells, including astrocytes, microglia, and oligodendrocytes. In its most extreme form, the proliferation associated with gliosis leads to the formation of a glial scar.
