Although we acknowledge that the present molecular classification of soft tissue tumours is much more complex than two decades ago, when EWSR1 gene rearrangements had been described as the hallmark of Ewing sarcoma, we make the strong argument that with very few exceptions, the prevalence of fusion transcripts in most sarcomas is such that they come to define these entities and can be used as highly specific molecular diagnostic markers in the right clinical and pathological context.
