Fluorescence in situ hybridization (FISH) analysis using the LSI EWSR1 break-apart probe and a reverse transcription polymerase chain reaction (RT-PCR) assay optimized for formalin-fixed paraffin-embedded tissue to detect all four reported EWSR1/ATF1 clear cell sarcoma chimeric types and the EWSR1/CREB1 variant was performed.     ///    One case carried a type 2 transcript alone and one case contained an EWSR1/CREB1 transcript.     ///    Detection and characterization of EWSR1/ATF1 and EWSR1/CREB1 chimeric transcripts in clear cell sarcoma (melanoma of soft parts)..     ///    "In addition, EWSR1-CREB1 was identified in a clear cell sarcoma of soft tissue providing further evidence that this chimeric variant is not exclusive to gastrointestinal clear cell sarcomas and should be included in RT-PCR assays of soft tissue clear cell sarcomas..
