This chapter provides a comprehensive overview of malignant gliomas, the most common primary brain tumor in adults. These tumors are varied in their cellular origin, genetic profile, and morphology under the microscope, but together they share some of the most dismal prognoses of all neoplasms in the body.

The authors present 2 patients. One of them had typical multifocal primary multiple synchronous wild-type IDH1/2 glioblastoma subtype RTK1, chromosome 7 duplication, homozygous CDKN2A deletion and chromosome 10 deletion. In another patient, the nature of tumors remains debatable.

Benign glioma broadly refers to a heterogeneous group of slow-growing glial tumors with low proliferative rates and a more indolent clinical course. These tumors may also be described as "low-grade" glioma (LGG) and are classified as WHO grade I or II lesions according to the Classification of Tumors of the Central Nervous System (CNS) (Louis et al. in

ABSTRACT:Light and electron microscopic studies in a case of nasal Glioma revealed a tumor composed nearly entirely of astrocytes. No ganglion cells or neurons were present and the mass was not surrounded by a capsule reminiscent for meningeal tissue. The vasculature resembled dermal patterns rather than typical central nervous system.

Gliomas are primary central nervous system tumors that arise from astrocytes, oligodendrocytes or their precursors. Gliomas can be classified into several groups according to their histologic characteristics, the most malignant of the gliomas is glioblastoma multiforme.

Primary tumors of the optic nerve are uncommon. The most common are optic nerve gliomas (ONGs), which account for 66% of all primary optic nerve tumors. Seventy-five percent of gliomas are diagnosed in the first decade of life, and 90% are diagnosed in the first two decades.

Brainstem gliomas, a relatively common form of childhood brain tumor, are highly resistant to therapy. With computed tomography and magnetic resonance imaging, these lesions can be diagnosed with a high degree of reliability. The indications for surgery are unclear. Focal lesions may be amenable to partial resections.

Gliomas are primary brain tumours that are thought to develop from neural stem or progenitor cells that carry tumour-initiating genetic alterations. Based on microscopic appearance and molecular characteristics, they are classified according to the WHO classification of central nervous system (CNS) tumours and graded into CNS WHO grades 1-4 from a low ...

An 11-month-old girl had a congenital extracranial frontonasal glioma. The tumor was attached to the left membranous septum and excised by a simple ellipse and stalk dissection. The tumor is considered to arise from ectopic neuroectodermal tissue projected through the foramen cecum into the developing nasofrontal cranium and sequestered there on ...
