Endometrial stromal tumors are reviewed with emphasis on their wide morphologic spectrum and problems in differential diagnosis, highlighting issues that have received particular attention in the recent literature. These neoplasms are divided into two major categories--endometrial stromal nodules and endometrial stromal sarcomas--a distinction made on the basis of the lack of significant infilt...

Hyperplasia of the endometrial stroma is a poorly recognized lesion, lacking widespread recognition with most, if not all, such cases sequestrated in the literature as endometrial stromal nodules or low-grade endometrial stromal sarcomas. In this paper, we describe three examples of "endometrial stromal hyperplasia" which have a remarkable morphological similarity with the normally proliferatin...

background: endometriosis is the presence of endometrial tissue outside of the uterine cavity and is the most common gynecologic disorder in women of reproductive age. we have preliminary evidence that in the presence of a 3-dimensional (3-d) fibrin matrix, human endometrial glands, stroma, and neovascularization can develop in vitro, mimicking the earliest stages of endometriosis. the aim of t...

We have investigated the possible roles of oncostatin M (OSM), which is a member of the interleukin-6 family of cytokines, in endometrial and endometriotic stromal cell growth. Endometrial and endometriotic stromal cells were collected from the uterus or ovarian chocolate cysts. We observed the expression of mRNA transcripts for OSM, OSM receptor subunit beta, leukaemia inhibitory factor recept...

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 of...

High-grade endometrial stromal sarcoma is a rare uterine malignancy. The cells of these tumors resemble endometrial cells in the proliferation stage, with many small plexiform arterioles. Herein we present a patient with endometrial stromal sarcoma that metastasized to the brain, along with the CT and MRI findings and a discussion of the surgical and histopathological features of the metastatic...

The endometrial stromal nodule is a benign tumor composed of differentiated endometrial stromal cells arranged as a well circumscribed nodule with smooth non-invasive margins. They are rare neoplasms, diagnosed in most instances by microscopy. Although nodules are benign in nature, hysterectomy is the treatment of choice to enable evaluation of the tumor margins which are well demarcated in end...

Runx3 is a transcription factor that belongs to the Runx family. We studied the localization of Runx3 mRNA in the mouse uterus, and its function in the mouse endometrium using Runx3 knockout (Runx3(-/-)) mice. Runx3 mRNA was detected in the endometrial luminal epithelial cells, glandular epithelial cells and stromal cells below the epithelial cell layer on the luminal side. The uteri of Runx3(-...

This report describes a uterine tumour exhibiting areas of both endometrial stromal and smooth muscle diVerentiation. There was extensive intravasular permeation within the myometrium as well as extrauterine vascular involvement. The endometrial stromal component had a myxoid appearance and the smooth muscle component exhibited the typical features of intravenous leiomyomatosis. An additional f...

The objective of the present study was to investigate the effects of insulin-like growth factor-binding protein-1 (IGFBP-1) on the interaction between mouse embryos and endometrial stromal cells in co-culture systems. To explore quantitatively the changes in expression of IGFBP-1 mRNA from endometrial stromal cells cultured alone or co-cultured with embryos, a combination of reverse transcripti...
