Endometrial stromal sarcoma (ESS) is a rare malignant neoplasm of the uterus. We report the first case of undifferentiated ESS (UES) coexistent with grade 1 endometrioid adenocarcinoma in a 73-year-old female who presented with irregular vaginal bleeding for 4 days after menopause 20 years. Imaging examination including Magnetic Resonance Imaging (MRI) demonstrated multi-node reflection in uter...

The presence of endometrial tissue outside of the uterine cavity is named endometriosis and is the most common gynecologic disorder in women. Determining the inhibitory effect of a Deforolimus on angiogenesis in a three-dimensional (3-D) culture of human endometrial stromal cells (hEnCs) in vitro. The important mechanism in the pathogenesis of endometriosis is angiogenesis, and deforolimus has ...

Corticotropin-releasing hormone (CRH) is a hypothalamic neuropeptide that has been identified also in several peripheral tissues, including organs of the reproductive system. In man, CRH is synthesized and released by the gonads, the placenta, maternal decidua, and the epithelial endometrium. So far, CRH has been demonstrated in endometrial stromal cells only after decidualization. The aim of t...

The proliferative activity in endometrial stromal granulocytes was studied using two approaches. Firstly, mitotic activity was studied in paraffin wax embedded sections of normal non-pregnant endometrium and early pregnancy decidua stained with phloxine-tartrazine. Secondly, the monoclonal antibody Ki67 was applied to cryostat sections of similar tissues. Endometrial stromal granulocytes were i...

background:   acute appendicitis with appendicial endometriosis is a very infrequently encountered condition during pregnancy. decidualization is the hypertrophy of endometrial stromal cells by the effect of progesterone. similarly, in pregnancy, ectopic stromal endometrial cells in endometriosis can also be transformed by the same mechanism and ectopic decidua (deciduosis) may occur case: here...

The human endometrium undergoes cyclic change during each menstrual cycle in response to gonadal steroids. Proteolysis of endometrial extracellular matrix (ECM) is necessary to prepare this dynamic tissue for pregnancy. Proteolytic enzymes such as matrix metalloproteinase (MMP) and closely related a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS) have been assigned key rol...

AIMS Cellular retinol-binding protein-1 (CRBP-1) contributes to the maintenance of the differentiated state of the endometrium through retinol bioavailability regulation. The aim was to analyse CRBP-1 expression in endometrial stromal cells at eutopic and ectopic sites in different physiopathological conditions. METHODS AND RESULTS Antibodies to CRBP-1, CD10 and alpha-smooth muscle actin were...

The development of endometrial stromal sarcomas (ESSs) in foci of endometriosis is extremely rare, and few cases have been reported in the literature to date, particularly with regard to multiple extrauterine ESS. Here we report a case of endometrial stromal sarcoma with multiple metastasis that arose from an ovarian endometriotic lesion. The literature is also briefly reviewed.
