JAZF1, YWHAE, and BCOR Gene Translocation in Primary Extrauterine Low-Grade and High-Grade Endometrial Stromal Sarcomas

In extrauterine low-grade endometrial stromal sarcoma (LG-ESS), the positive rate of JAZF1 gene rearrangement was significantly lower than in uterine LG-ESS, limiting the value of JAZF1 gene translocation for diagnosis.
