 BCOR-CCNB3 fusion transcripts resulting from an X-chromosomal paracentric inversion were recently identified in a series of unclassifiable soft tissue and bone sarcomas with Ewing sarcoma-like morphology.     ///    "Reverse transcription polymerase chain reaction for BCOR-CCNB3 fusion transcripts was positive in all 9 cases, which yielded sufficient extracted RNA. "    ///    "In conclusion, this study provides a detailed description of the histologic spectrum, immunohistochemical features, and clinical characteristic of BCOR-CCNB3 sarcoma justifying distinction from Ewing sarcoma with its typical EWS/FUS-ETS translocations. "    ///    BCOR-CCNB3 sarcomas located in axial skeleton and soft tissues showed a significantly shorter survival.     ///    "BCOR-CCNB3 (Ewing-like) sarcoma: a clinicopathologic analysis of 10 cases, in comparison with conventional Ewing sarcoma.. "    ///    "The Ewing sarcoma overall survival was not statistically different, although there was a trend for longer survival of patients with BCOR-CCNB3 sarcomas in the extremities. "    ///    Here we describe the clinicopathologic features of 10 cases of BCOR-CCNB3 sarcoma and compare their clinical course with typical Ewing sarcoma.
