Translocations involving BCOR have been detected in different types of sarcoma such as OFMT and entities of the group of undifferentiated small round cell sarcomas (URCS), which in the past, also because of their CD99 positivity and other similarities with Ewing sarcoma (EwS), have been termed as “Ewing-like sarcoma”. Here, BCOR is linked to Ewing sarcoma.
