Abstract
Ependymal tumors are classified based on their location, histology, and molecular characteristics. Supratentorial ependymomas (ST-EPNs) are a group of circumscribed supratentorial gliomas, which usually have pathogenic fusions involving either zinc finger translocation associated (ZFTA) (formerly C11orf95) or YAP1. A subtype of ependymoma was recently described and labeled ependymoma-like tumors with mesenchymal differentiation (ELTMDs). We describe a case of a 5-year-old boy who presented with a right frontal tumor. The diagnosis was challenging, and a correct diagnosis could only be reached after reanalysis of methylation data with a more recent version of the classifier and RNA fusion testing, which revealed ZFTA:NCOA1 (nuclear receptor coactivator 1) fusion. There are only a handful of cases of this entity, which is being reported for its rarity and the diagnostic challenge it poses.
期刊介绍：
Neuropathology is an international journal sponsored by the Japanese Society of Neuropathology and publishes peer-reviewed original papers dealing with all aspects of human and experimental neuropathology and related fields of research. The Journal aims to promote the international exchange of results and encourages authors from all countries to submit papers in the following categories: Original Articles, Case Reports, Short Communications, Occasional Reviews, Editorials and Letters to the Editor. All articles are peer-reviewed by at least two researchers expert in the field of the submitted paper.
