Pediatric gliomas, consisting of both pediatric low-grade (pLGG) and high-grade gliomas (pHGG), are the most frequently occurring brain tumors in children. Over the last decade, several milestone advancements in treatments have been achieved as a result of stronger understanding of the molecular biology behind these tumors. This review provides an overview of pLGG and pHGG highlighting their clinical presentation, molecular characteristics, and latest advancements in therapeutic treatments. Conclusion: The increasing understanding of the molecular biology characterizing pediatric low and high grade gliomas has revolutionized treatment options for these patients, especially in pLGG. The implementation of next generation sequencing techniques for these tumors is crucial in obtaining less toxic and more efficacious treatments. What is Known: • Pediatric Gliomas are the most common brain tumour in children. They are responsible for significant morbidity and mortality in this population. What is New: • Over the last two decades, there has been a significant increase in our global understanding of the molecular background of pediatric low and high grade gliomas. • The implementation of next generation sequencing techniques for these tumors is crucial in obtaining less toxic and more efficacious treatments, with the ultimate goal of improving both the survival and the quality of life of these patients.

Introduction: Diffuse intrinsic pontine glioma (DIPG) in children comprises 80% of brainstem gliomas. In 2021, 5th edition of WHO CNS tumor classification defined H3K27M altered diffuse midline gliomas (DMGs) which replaced this entity. Lesion location precludes resection and the only current option available is radiotherapy.

Six-transmembrane epithelial antigen of prostate 3 (STEAP3), a member of the iron regulation protein family, is characterized by a high recurrence rate and a short survival time. Nevertheless, studies investigating the role of STEAP3 in glioblastoma (GB) are scarce. In this study, the prognostic value of STEAP3 was evaluated utilizing mRNA expression profiles from Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) databases as the validation and training cohorts, respectively.

Serine 31 is a phospho-site unique to the histone H3.3 variant; mitotic phospho-Ser31 is restricted to pericentromeric heterochromatin, and disruption of phospho-Ser31 results in chromosome segregation defects and loss of p53-dependant G cell-cycle arrest. Ser31 is proximal to the H3.

Various space occupying lesions can arise in the orbit, ranging from developmental anomalies to malignancies, and many of the diseases occurring in children are different from the pathologies in the adult population. As the clinical presentation is frequently nonspecific, radiologic evaluation is essential for lesion detection and characterization as well as patient management. While orbital masses may in some cases involve multiple compartments, a simple compartmental approach is the key for the diagnosis on imaging studies, and MRI is the modality of choice.

Radiotherapy is a rare cause of Stevens-Johnson syndrome (SJS)/ toxic epidermal necrolysis (TEN), especially in the pediatric age group. Most of the reported cases were concomitantly started on anti-epileptic drugs. Herein, we present a case of radiotherapy induced SJS/TEN in an adolescent girl in the absence of anti-epileptic drug use.
