Endometrial hyperplasia is a condition of excessive proliferation of the cells of the endometrium, or inner lining of the uterus.. Most cases of endometrial hyperplasia result from high levels of estrogens, combined with insufficient levels of the progesterone-like hormones which ordinarily counteract estrogen's proliferative effects on this tissue.
Atypical endometrial hyperplasia may represent an early neoplastic process which can lead to endometrial adenocarcinoma. [20] The development of endometrial adenocarcinoma from endometrial hyperplasia is a typical example of how the effects of pathologic hyperplasia can lead to neoplasia, and females who exhibit hyperplasia of the endometrium ...
Uterine hyperplasia, or enlarged uterus, is a medical symptom in which the volume and size of the uterus in a female is abnormally high. It can be a symptom of medical conditions such as adenomyosis , uterine fibroids , ovarian cysts , and endometrial cancer .
Type II endometrial carcinomas usually occur in older, post-menopausal people, in the United States are more common in black women, and are not associated with increased exposure to estrogen or a history of endometrial hyperplasia. Type II endometrial cancers are often high-grade, with deep invasion into the underlying uterine wall (myometrium ...
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 ...
Adenomyosis is a medical condition characterized by the growth of cells that proliferate on the inside of the uterus (endometrium) atypically located among the cells of the uterine wall , [2] as a result, thickening of the uterus occurs. As well as being misplaced in patients with this condition, endometrial tissue is completely functional.
Uterine adenomyoma, the localized form of uterine adenomyosis, is a tumor composed of endometrial gland tissue and smooth muscle in the myometrium. [2] Adenomyomas containing endometrial glands are also found outside of the uterus, most commonly on the uterine adnexa but can also develop at distant sites outside of the pelvis. [3]
