A recently characterized group of undifferentiated small round cell sarcomas harbours fusions of the genes CIC and DUX4. Studies report a distinctive gene expression profile for these sarcomas, including expression of E26 transformation‐specific (ETS) family proto‐oncogenic transcription factors ETV1, ETV4 and ETV5. To test the utility of an ancillary diagnostic technique for these tumours, we evaluated chromogenic RNA in‐situ hybridization assays for ETV1, ETV4 and ETV5 as diagnostic adjuncts for this emerging group of highly malignant sarcomas.
