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 ...
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 .
Endometrial hyperplasia – Hyperproliferation of the endometrium, usually in response to unopposed estrogen stimulation in the setting of polycystic ovary syndrome or exogenous administration of hormones. Atypical endometrial hyperplasia may represent an early neoplastic process which can lead to endometrial adenocarcinoma. [20]
Hormonal hyperplasia occurs mainly in organs that depend on estrogen. For example, the estrogen-dependent uterine cells undergo hyperplasia and hypertrophy following pregnancy. Pathologic hyperplasia is an abnormal increase in cell division. A common pathologic hyperplasia in women occurs in the endometrium and is called endometriosis. [7]
Endometrial hyperplasia; Endometrial cancer is the most common cancer of the human female genital tract. Asherman's syndrome, also known as intrauterine adhesions, ...
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.
It is distinguished from hyperplasia, in which the cells remain approximately the same size but increase in number. [2] Although hypertrophy and hyperplasia are two distinct processes, they frequently occur together, such as in the case of the hormonally induced proliferation and enlargement of the cells of the uterus during pregnancy.
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 ...
