Gliosarcoma is a rare type of glioma, a cancer of the brain that comes from glial, or supportive, brain cells, as opposed to the neural brain cells. Gliosarcoma is a malignant cancer, and is defined as a glioblastoma consisting of gliomatous and sarcomatous components. [3]
The International Classification of Diseases for Oncology (ICD-O) is a domain-specific extension of the International Statistical Classification of Diseases and Related Health Problems for tumor diseases. This classification is widely used by cancer registries. It is currently in its third revision (ICD-O-3). ICD-10 includes a list of ...
Glioblastoma pre (left) and post (right) resection. Surgery is the first stage of treatment of glioblastoma. An average GBM tumor contains 10 11 cells, which is on average reduced to 10 9 cells after surgery (a reduction of 99%). Benefits of surgery include resection for a pathological diagnosis, alleviation of symptoms related to mass effect ...
Astrocytomas: astrocytes (glioblastoma multiforme is a malignant astrocytoma and the most common primary brain tumor among adults). Oligodendrogliomas: oligodendrocytes; Brainstem glioma: develop in the brain stem; Optic nerve glioma: develop in or around the optic nerve; Chordoid glioma, a rare low-grade tumor of the third ventricle [54]
The concept of grading of the tumors of the central nervous system, agreeing for such the regulation of the "progressiveness" of these neoplasias (from benign and localized tumors to malignant and infiltrating tumors), dates back to 1926 and was introduced by P. Bailey and H. Cushing, [1] in the elaboration of what turned out the first systematic classification of gliomas.
The giant-cell glioblastoma is a histological variant of glioblastoma, presenting a prevalence of bizarre, multinucleated (more than 20 nuclei) giant (up to 400 μm diameter) cells. It occasionally shows an abundant stromal reticulin network and presents a high frequency of TP53 gene mutations .
Gliomatosis cerebri is most often caused by glioblastoma, but can also arise from astrocytoma, oligodendroglioma or other types of diffuse glioma. [2] Other pathologies such as vasculitis , encephalitis or leukoencephalopathy may also cause similar radiological findings.
