Identification of novel FGFR2::TXLNB Fusion in a polymorphous low-grade neuroepithelial tumor of the young. [PDF]
Brain PatholWe report a novel FGFR2::TXLNB fusion in a child with hippocampal PLNTY. This fusion likely drives tumorigenesis via homodimerization and activation of MAPK/PI3K pathways, expanding PLNTY's molecular spectrum and suggesting a potential therapeutic target.

A rare case of dysembryoplastic neuroepithelial tumor combined with encephalocraniocutaneous lipomatosis and intractable seizures [PDF]
Korean Journal of Pediatrics, 2016 Encephalocraniocutaneous lipomatosis (ECCL) is a rare neurocutaneous syndrome that affects ectomesodermal tissues (skin, eyes, adipose tissue, and brain). The neurologic manifestations associated with ECCL are various including seizures.

Collision Glial Neoplasms Arising in an Ovarian Mature Cystic Teratoma: A Rare Event
Case Reports in Pathology, 2020 Germ cell neoplasms represent around 20% of all ovarian tumors. They most frequently affect children and young adults. Mature cystic teratoma is a common benign ovarian neoplasm comprising about 95% and is made up of all three germ cell embryonic layers.

Pigmented olfactory neuroblastoma. A new example of melanotic neuroepithelial neoplasm [PDF]
Cancer, 1982 The light and electron microscopic features of a pigmented olfactory neuroblastoma are described. The neuroblastic nature of the tumor was confirmed by the demonstration of axons, some of which originated from the neoplastic cells, and by the presence of dense-core vesicles in the perikarya and processes of the tumor cells.

Duplications of KIAA1549 and BRAF screening by Droplet Digital PCR from formalin-fixed paraffin-embedded DNA is an accurate alternative for KIAA1549-BRAF fusion detection in pilocytic astrocytomas [PDF]
, 2018 Pilocytic astrocytomas represent the most common glioma subtype in young patients and account for 5.4% of all gliomas. They are characterized by alterations in the RAS–MAP kinase pathway, the most frequent being a tandem duplication on chromosome 7q34 ...
