Supratentorial embryonal tumors are very rare malignant tumors of neuroectodermal origin, characterized by an aggressive clinical behavior. They occur prevalently in children. They have been sporadically described in adults and represent an even rarer occurrence in elderly patients, raising many issues on the diagnostic pitfalls and their appropriate management. We present an unusual case of embryonal tumor in a 62-year-old man who presented with speech disorder, and partial deficit of the left 3rd and 5th cranial nerves secondary to a left temporo-insular embryonal tumor: the clinico-radiological features, histopathological insights, therapeutic options and results are discussed along with a review of the most relevant literature, addressing the specific issue of differential diagnosis and the expected results in the elderly population.

Article Synopsis
- * A 17-year-old male presented with headaches and walking difficulties, leading to the discovery of a CPA lesion, which was surgically removed and diagnosed as medulloblastoma; he then received chemo-radiotherapy.
- * After two years, the patient experienced new headaches and seizures, resulting in the identification of a metastatic tumor in the temporal lobe, also confirmed as medulloblastoma.

Article Synopsis
- Recent cases suggest that high-grade supratentorial tumors in infants with specific ZFTA::NCOA1/2 fusions are categorized as ependymoma-like tumors with mesenchymal differentiation (ELTMDs).
- This study presents a unique case in a 30-year-old woman showing mixed tumor components and a novel ZFTA::RELA fusion, differentiating it from traditional ependymomas.
- The findings support classifying this case under ELTMD, marking it as the first adult instance analyzed through DNA methylation profiling, highlighting the potential recognition of ELTMD as a new type of tumor.

Neuroepithelial tumors with fusion of PLAGL1 or amplification of PLAGL1/PLAGL2 have recently been described often with ependymoma-like or embryonal histology respectively. To further evaluate emerging entities with PLAG-family genetic alterations, the histologic, molecular, clinical, and imaging features are described for 8 clinical cases encountered at St. Jude (EWSR1-PLAGL1 fusion n = 6; PLAGL1 amplification n = 1; PLAGL2 amplification n = 1).

A novel histomolecular tumor of the central nervous system (CNS), the "diffuse glioneuronal tumor with oligodendroglioma-like features and nuclear clusters (DGONC)," has recently been identified, based on a distinct DNA methylation profile and has been added to the 2021 World Health Organization Classification of CNS Tumors. This glioneuronal tumor mainly affects the supratentorial area in children and recurrently presents with a monosomy of chromosome 14. Herein, we report the case of a DNA-methylation based diagnosis of DGONC having atypical features, such as pseudo-rosettes and the absence of a chromosome 14 monosomy, thus rendering its diagnosis very challenging.

Background: ETMR is a unique and highly malignant brain tumor mostly occurring in infants. This report provides a comprehensive overview of the clinical presentation, histological aspects, radiological features, and therapeutic options of ETMR. Being the first report on the co-occurrence of NF1 with ETMR, it highlight the challenges of managing a patient with complex medical conditions.
