The consolidation came amid mounting evidence that these 2 mesenchymal tumors are closely related, or even identical, entities. These neoplasms demonstrate significant clinical and demographic overlap, often indistinguishable imaging features, and a shared nerve growth factor inducible-A-binding protein 2/signal transducer and activator of transcription 6 gene fusion. We presented 2 cases of this uncommon entity and discussed its evolving tumor classification.", }
