Astrocytoma Polymorphic Cellular

Polychrome cellular astrocytoma is an interdisciplinary category of pathology from the group of brain tumors. It belongs to secondary malignant neoplasms and is composed of fragments of the membranes of neurons (astrocytes). This glial tumor arises from astrocyte cells and is most often diagnosed between two and seven years of the patient's life.

*Etiology*. In 93.2% of cases, the disease occurs between 40–50 years. The prerequisites for the creation of this form of neoplasms have not been precisely established. According to scientists, the disease can appear after infectious diseases of the nervous system, as well as under the influence of carcinogenic and mutagenic factors. It has been shown that the disease appears more often in males than in females. This is due to the fact that men experience alcohol and drug intoxication more often than women. The tumor tends to appear on both hemispheres and usually on the right. The form of the disease is polymorphic cellular in the cortex, parietal, occipital and frontal lobes, and is also found in the internal capsule. Topographically, the tumor mainly affects the parietal zone. It is also relatively often located on the periphery of the temporal, vertex, and frontal areas.
