Tuesday 14 May 2013
- Endometrial stromal sarcomas represent the second most common mesenchymal uterine tumor.
- The 2003 WHO classification distinguishes low-grade and undifferentiated endometrial stromal sarcomas with different prognoses.
- Endometrial stromal sarcomas are a genetically heterogeneous group of sarcomas harboring different cytogenetic anomalies.
- A fusion between the YWHAE and FAM22A/B genes subsequent to a t(10;17) (q22;p13) has been described in endometrial sarcomas with high-grade histology.
