Reverse transcription-polymerase chain reaction (RT-PCR) was applied for detection of expression of JAZF1-SUZ12 and YWHAE-FAM22 fusion genes in 47 cases of ESS and 12 cases of other spindle cell neoplasia in uterus (including 2 cases of undifferentiated sarcoma, 3 cases of leiomyosarcoma, 3 cases of leiomyoma, 4 cases of adenosarcoma and 2 cases of uterine tumor resembling ovarian sex cord tumor).     ///    [Endometrial stromal sarcoma: morphologic features and detection of JAZF1-SUZ12 and YWHAE FAM22 fusion genes]..     ///    " To study the morphologic features, immunophenotype and significance of expression of JAZF1-SUZ12 and YWHAE-FAM22 fusion genes in endometrial stromal sarcoma (ESS). "    ///    The 14 control cases were all negative for JAZF1-SUZ12 and YWHAE-FAM22 fusion genes.     ///    The positive rate of JAZF1-SUZ12 fusion gene was 30.8% (12/39) in low-grade ESS.
