Using reverse transcription-polymerase chain reaction (RT-PCR) and subsequent sequencing, we confirmed an identical WWTR1-CAMTA1 fusion transcript product from different nodules in each patient.     ///    Our recent identification of a WWTR1-CAMTA1 fusion as the genetic hallmark of EHE irrespective of anatomic location was used to clarify this question by comparing the similarity of translocation breakpoints.     ///    Monoclonality of multifocal epithelioid hemangioendothelioma of the liver by analysis of WWTR1-CAMTA1 breakpoints..
