Core Tip

Core tip: Endometrial stromal sarcomas are common tumours. Metastatic low-grade endometrial stromal sarcoma (LG-ESS) with sex cord and smooth muscle differentiation, however, is an extremely rare diagnosis. To date, only two cases have been reported in the literature. Histopathologic examination revealed a uterine leiomyoma within a pelvic mass. LG-ESS with sex cord-like differentiation should be distinguished from uterine tumor resembling ovarian sex cord tumor.
