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.
Endometrial Topography Functional Category Treatment Benign endometrial hyperplasia: Diffuse: Hormone (estrogen) Effect: Hormonal therapy EIN, Endometrial Intraepithelial Neoplasia: Focal progressing to diffuse (clonal) Precancer: Hormonal or surgical Endometrial Adenocarcinoma: Focal progressing to diffuse (clonal) Cancer: Surgical stage-based
There are a number of indications for obtaining an endometrial biopsy from a non-pregnant woman: [citation needed]. Women with chronic anovulation such as the polycystic ovary syndrome are at increased risk for endometrial problems and an endometrial biopsy may be useful to assess their lining specifically to rule out endometrial hyperplasia or cancer.
Hyperplasia of the breast – "Hyperplastic" lesions of the breast include usual ductal hyperplasia, a focal expansion of the number of cells in a terminal breast duct, and atypical ductal hyperplasia, in which a more abnormal pattern of growth is seen, and which is associated with an increased risk of developing breast cancer.
Metropathia haemorrhagica, also known as metropathia haemorrhagica cystica, is a menstrual disorder which is defined as a specialized type of anovulatory dysfunctional uterine bleeding associated with endometrial hyperplasia and intermenstrual bleeding.
Serous carcinoma is a Type II endometrial tumor that makes up 5–10% of diagnosed endometrial cancer and is common in postmenopausal women with atrophied endometrium and black women. Serous endometrial carcinoma is aggressive and often invades the myometrium and metastasizes within the peritoneum (seen as omental caking ) or the lymphatic system.
Detection by ultrasonography can be difficult, particularly when there is endometrial hyperplasia (excessive thickening of the endometrium). [2] Larger polyps may be missed by curettage. [10] Endometrial polyps can be solitary or occur with others. [11] They are round or oval and measure between a few millimeters and several centimeters in ...
Endometrial proliferation is also led by estrogen; some treatments try to reduce its levels in order to decrease symptoms. [6] Adenomyosis patients present with heavy menstrual bleeding due to the increase of endometrial tissue, greater degree of vascularization, atypical uterine contractions and increased levels of prostaglandins, estrogen and ...
