Diffuse astrocytoma (DA) is a rare low-grade astrocytoma with high cellular differentiation, slow growth, and extensive infiltration of neighbouring brain areas. Despite being classified as grade II diffuse astrocytoma by the World Health Organization, these neoplasms in children are clinically and molecularly differ from those in adults. They seldom proceed to higher grade lesions and infrequently have an IDH mutation. DA is most common in young people, although it can also occur in youngsters and the elderly. They can be found everywhere in the brain, but they are most frequent in the cerebral hemispheres - the "thinking" section. The margins of a diffuse astrocytoma tend to expand into surrounding normal brain tissue, as the term indicates. Seizures and migraines are frequently the first symptoms of this tumor, as well as paralysis on one side of the body (hemiparesis). Here, we discuss the clinical, histologic, and molecular characteristics of grade II diffuse astrocytoma, stressing its diagnostic criteria, prevalence across brain sites, most prevalent molecular characteristics, how to screen for it, and the influence of surgical resection of DA on the treatment.
