PURPOSE The goal of this study was to perform a retrospective analysis of the ultrasonographic findings associated with low-grade endometrial stromal sarcoma. METHODS Ten pathologically confirmed cases of low-grade endometrial stromal sarcoma at our institution from January 2007 to April 2014 were retrospectively reviewed. All patients underwent a preoperative transvaginal ultrasound. Two rad...

Endometrial stromal tumor is an uncommon uterine tumor comprising <10% of all uterine mesenchymal neoplasms. The diagnosis of low-grade endometrial stromal sarcoma (LGESS) is based on characteristic histopathological features showing diffuse growth of uniform stromal cells resembling those of proliferative phase endometrium and uniformly distributed small spiral arterioles and it is not problem...

Endometrial stromal nodule (ESN) is the least common of the endometrial stromal tumors. They are rare neoplasms which are diagnosed in most instances by light microscopy. Although such nodules are benign, hysterectomy has been considered the treatment of choice to determine the margins of the tumor required for diagnosis and to differentiate it from invasive stromal sarcoma Whose prognosis is t...

Introduction: Endometrial stromal sarcomas usually arise in the uterine corpus while it is rare in extra-uterine sites. The most common extra-uterine site is the ovary. However, primary endometrial stromal sarcoma of the ovary rarely arises in a serous tumor. We report a case of primary ovarian ESS presenting in the wall of a serous cyst along with a synchronous endometrial stromal nodule (ESN)...

BACKGROUND The existence of stem/progenitor cells in the endometrium was postulated many years ago, but the first functional evidence was only published in 2004. The identification of rare epithelial and stromal populations of clonogenic cells in human endometrium has opened an active area of research on endometrial stem/progenitor cells in the subsequent 10 years. METHODS The published liter...

BACKGROUND Repeated Implantation Failure (RIF) is one of the most intricate obstacles in assisted reproduction. The cytokine and chemokine composition of uterine cavity seem to play important roles in the implantation process. OBJECTIVE To compare the cytokine profile in the endometrium of normal fertile women and those with repeated implantation failure. METHODS After enzymatic digestion o...

Matrix metalloproteinase (MMP)-2 and -9 are secreted and translocated from endometrial stromal cells to HEC-1 A cells in a steroid-dependent manner. We investigated the paracrine effect of hepatocyte growth factor (HGF) on MMPs and metalloproteinase tissue inhibitor (TIMP) expression in stromal and endometrial cancer cells, and correlated with cancer cell invasiveness in three-dimensional (3D) ...

Prokineticin 1 (PROK1), a hypoxia-regulated angiogenic factor, has emerged as a crucial regulator of embryo implantation and placentation. Dysregulation of PROK1 has been linked to recurrent pregnancy loss, pre-eclampsia, foetal growth restriction and preterm birth. These pregnancy complications are common in women with obesity and polycystic ovary syndrome, i.e. conditions associated with insu...

When Fas ligand (FasL) interacts with the Fas receptor, it induces apoptosis through autocrine and/or paracrine signalling. Vascular endothelial growth factor (VEGF) is a potent mitogenic cytokine. VEGF plays a role during remodelling of the endometrium following menstruation. We hypothesized that, by regulating FasL expression, VEGF may play a role in endometrial stromal cell survival by decre...
