Adamantinoma‑like Ewing Sarcoma of Head and Neck: A Clinicopathologic Study of Three Cases Including One EWSR1-Negative Case with NF1 Mutation
“Reporting on the latest medical advancements, researchers have made significant strides in understanding Adamantinoma-like Ewing sarcoma (ALES), a rare form of cancer. The study, which involved three cases of head and neck ALES, revealed a wide range of histological features and variable immunohistochemical expressions. Notably, it identified a case with a somatic NF1 mutation but without the typical EWSR1 rearrangement, broadening the molecular understanding of ALES. This discovery underscores the diagnostic complexity and the critical need for comprehensive molecular profiling, including next-generation sequencing, to ensure accurate diagnosis and to uncover potential therapeutic targets.”
