We present an ossifying fibromyxoid tumor case with the EP400-PHF1 fusion gene detected by reverse transcriptase polymerase chain reaction, along with compatible cytogenetic data showing a t(6;12)(p21;q24.3) translocation.     ///    Ossifying fibromyxoid tumor presenting EP400-PHF1 fusion gene..     ///    Our results suggest that the EP400-PHF1 fusion gene is a reproducible finding in ossifying fibromyxoid tumor.     ///    "Recently, a novel fusion gene, EP400-PHF1, was discovered in ossifying fibromyxoid tumor. "    ///    "however, its relation to this type of tumor has been uncertain because the EP400-PHF1 fusion gene has been successfully detected in only 1 case. "
