Endometrial Stromal Nodule. An endometrial stromal nodule is a noninfiltrative, circumscribed proliferation of endometrial stromal cells and is a benign subtype of endometrial stromal tumor. The appearance of the cells is identical to normal endometrial stromal cells. This can only be differentiated from low-grade endometrial stromal sarcoma by ...
Decidualization is a process that results in significant changes to cells of the endometrium in preparation for, and during, pregnancy. This includes morphological and functional changes (the decidual reaction) to endometrial stromal cells (ESCs), the presence of decidual white blood cells (leukocytes), and vascular changes to maternal arteries.
Endometrial intraepithelial neoplasia (EIN) is a premalignant lesion of the uterine lining that predisposes to endometrioid endometrial adenocarcinoma. It is composed of a collection of abnormal endometrial cells, arising from the glands that line the uterus , which have a tendency over time to progress to the most common form of uterine cancer ...
The corresponding specific proteins are expressed in the glandular and stromal cells of the endometrial mucosa. The expression of many of these proteins vary depending on the menstrual cycle, for example the progesterone receptor and thyrotropin-releasing hormone both expressed in the proliferative phase, and PAEP expressed in the secretory phase.
Endometrial stromal tumours are a type of mesenchymal tumor of the main body of the uterus. [1] Types include endometrial stromal nodule , the distinct low and high-grade endometrial stromal sarcomas , and undifferentiated uterine sarcoma.
Surface epithelial-stromal tumors are a class of ovarian neoplasms that may be benign or malignant. Neoplasms in this group are thought to be derived from the ovarian surface epithelium (modified peritoneum) or from ectopic endometrial or fallopian tube (tubal) tissue. Tumors of this type are also called ovarian adenocarcinoma. [1]
Leiomyoma is the most common benign mesenchymal tumor of esophagus and second most common benign tumor of the small bowel (with gastrointestinal stromal tumor as most common). [7] Although leiomyoma is the most common benign esophageal tumor, malignant carcinoma is still 50 times more likely. [8]
Benign gynecological conditions include fecal incontinence, urinary incontinence, uterine and/or vaginal wall prolapse, interstitial cystitis, irritable bowel syndrome, diverticulitis, benign ovarian masses, uterine fibroids, endometriosis, ectopic pregnancy, pelvic inflammatory disease, adenomyosis, endometrial polyps, and endometrial ...
