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.
The endometrium is the inner epithelial layer, along with its mucous membrane, of the mammalian uterus.It has a basal layer and a functional layer: the basal layer contains stem cells which regenerate the functional layer. [1]
The part of the Fallopian tube that is located in the uterine wall and connects the remainder of the tube to the endometrial cavity is called its "interstitial" part, hence the term "interstitial pregnancy"; it has a length of 1–2 cm and a width of 0.7 cm. [1] Its borders are the opening (ostium) of the tube to the endometrial cavity within the uterus and, laterally, the visible narrow ...
An endometrial polyp or uterine polyp is a mass in the inner lining of the uterus. [1] They may have a large flat base or be attached to the uterus by an elongated pedicle (pedunculated). [2] [3] Pedunculated polyps are more common than sessile ones. [4] They range in size from a few millimeters to several centimeters. [3]
Endometritis is inflammation of the inner lining of the uterus (endometrium). [6] Symptoms may include fever, lower abdominal pain, and abnormal vaginal bleeding or discharge. [1] [4] It is the most common cause of infection after childbirth. [7] [1] It is also part of spectrum of diseases that make up pelvic inflammatory disease. [8]
The primary symptoms are those that are directly caused because of the defect in the wall of the uterus. These are postmentrual spotting , pain during menstrual bleeding, technical difficulty inserting the catheter during embryo transfer and secondary unexplained infertility combined with intrauterine fluid (fluid inside of the uterine cavity ...
Uterine glands or endometrial glands are tubular glands, lined by a simple columnar epithelium, found in the functional layer of the endometrium that lines the uterus. Their appearance varies during the menstrual cycle. During the proliferative phase, uterine glands appear long due to estrogen secretion by the ovaries.
The underlying causes may include ovulation problems, fibroids, the lining of the uterus growing into the uterine wall, uterine polyps, underlying bleeding problems, side effects from birth control, or cancer. [3] More than one category of causes may apply in an individual case. [3] The first step in work-up is to rule out a tumor or pregnancy.
