“…Gangliogliomas are rare tumors of the CNS. They can occur anywhere in the CNS but are usually found in the temporal lobe of children [ 16 ]. On histopathology examination, these were also confirmed by the presence of neoplastic ganglion cells and neoplastic glial component with IHCs showing both glial and neuronal components.…”

Introduction Central nervous system (CNS) lesions are rare and histologically heterogenous, and carry serious potential for patient morbidity and mortality. A retrospective epidemiological review of CNS neoplasms is of great importance for future research because it can demonstrate the changes in the spectrum of CNS lesions of a population, unveil the possible associated risk factors, and indicate the potential therapeutic methods for various neoplastic and non-neoplastic lesions. Neurosurgeons have always shown an obsession with a good neuropathological diagnosis in intracranial and extracranial lesions. This obsession need not be overemphasized as it helps the clinician plan an adequate surgical/treatment strategy to optimize outcomes and minimize morbidity. Methods This study included a spectrum of 160 biopsies of patients with space-occupying lesions of the CNS during a period of two years (2019-2021). All the cases were studied and analyzed, and their histological typing/grading was done. The cases were graded and categorized according to the 2016 WHO Classification of CNS Tumors. Results Among 160 cases, the study showed a slight male preponderance of 100 (62.5%) cases. The maximum number of cases, 37 (23%) cases, was in the age group of 41-50 years. Clinically, the commonest complaints were headache and seizures. The most common location of tumor was supra-tentorial, comprising around 96 (60%) cases, of which 27 (28%) cases were located in the frontal lobe. There were four (2.5%) cases that had non-neoplastic lesions and the rest 156 (97.5%) cases had neoplastic lesions. Malignant lesions outnumbered the benign lesions, comprising of 82 (51.25%) cases. Among the neoplastic lesions, the highest cases were of astrocytoma, 48 (30.76%) cases, followed by meningioma, 42 (26.92%) cases. Also, 21 extremely rare and unusual cases were encountered. Conclusion The present study reflects the diversity of histopathological spectrum of CNS lesions in our center. In-depth studies from across various hospitals are required to have representative data on the incidence, epidemiological profile, and etiology of CNS lesions in India.

“…Ependydoma is the most common in children originating from the cells lining the cavities of the brain and spinal canal. Ganglioglioma is the rarest form of glioma known, which originates from both glial and nerve cells 18 . Gliomas are usually graded from I to IV (Grade IV being the most aggressive type) based on the extent of cell proliferation, angiogenesis and necrosis 19 .…”

Stress granules (SGs) contain mRNAs and proteins stalled in translation during stress; these are increasingly being implicated in diseases, including neurological disorders and cancer. The dysregulated assembly, persistence, disassembly and clearance of SGs contribute to the process of senescence. Senescence has long been a mysterious player in cellular physiology and associated diseases. The systemic process of aging has been pivotal in the development of various neurological disorders like age‐related neuropathy, Alzheimer's disease and Parkinson's disease. Glioma is a cancer of neurological origin with a very poor prognosis and high rate of recurrence, SGs have only recently been implicated in its pathogenesis. Senescence has long been established to play an antitumorigenic role, however, relatively less studied is its protumorigenic importance. Here, we have evaluated the existing literature to assess the crosstalk of the two biological phenomena of senescence and SG formation in the context of tumorigenesis. In this review, we have attempted to analyze the contribution of senescence in regulating diverse cellular processes, like, senescence associated secretory phenotype (SASP), microtubular reorganization, telomeric alteration, autophagic clearance and how intricately these phenomena are tied with the formation of SGs. Finally, we propose that interplay between senescence, its contributing factors and the genesis of SGs can drive tumorigenicity of gliomas, which can potentially be utilized for therapeutic intervention.
