Bone and Soft Tissue: Ewing-like sarcoma

Abstract

Ewing-like sarcoma is a recently defined subset of bone or soft tissue sarcomas. It is one of the pediatric small, round, blue cell tumors and is fusion genedriven cancer. However, the driving fusions are distinct from that of the FET-ETS family rearrangements that define Ewing sarcoma (see separate entry for Ewing sarcoma).
