A benign condition in which tissue that looks like endometrial tissue grows in abnormal places in the abdomen.

A condition in which functional endometrial tissue is present outside the UTERUS. It is often confined to the PELVIS involving the OVARY, the ligaments, cul-de-sac, and the uterovesical peritoneum.

Condition in which tissue more or less perfectly resembling the uterine mucous membrane (the endometrium) and containing typical endometrial granular and stromal elements occurs aberrantly in various locations in the pelvic cavity.

The growth of endometrial tissue outside the uterus.

The growth of functional endometrial tissue in anatomic sites outside the uterine body. It most often occurs in the pelvic organs.

The uterus, or womb, is the place where a baby grows when a woman is pregnant. It is lined with tissue (endometrium). Endometriosis is a disease in which tissue that is similar to the lining of the uterus grows in other places in your body. These patches of tissue are called "implants," "nodules," or "lesions." They are most often found On or under the ovaries; On the fallopian tubes, which carry egg cells from the ovaries to the uterus; Behind the uterus; On the tissues that hold the uterus in place; On the bowels or bladder. In rare cases, the tissue may grow on your lungs or in other parts of your body. The cause of endometriosis is unknown. Endometriosis is most commonly diagnosed in women in their 30s and 40s. But it can affect any female who menstruates. Certain factors can raise or lower your risk of getting it. You are at higher risk if You have a mother, sister, or daughter with endometriosis; Your period started before age 11; Your monthly cycles are short (less than 27 days); Your menstrual cycles are heavy and last more than 7 days. You have a lower risk if You have been pregnant before; Your periods started late in adolescence; You regularly exercise more than 4 hours a week; You have a low amount of body fat.

In endometriosis, functioning endometrial tissue is implanted in the pelvis outside the uterine cavity. Symptoms depend on location of the implants and may include dysmenorrhea, dyspareunia, infertility, dysuria, and pain during defecation. Severity of symptoms is not related to disease stage. Diagnosis is by direct visualization and...

Ectopic endometrial tissues are most commonly located in the dependent portions of the female pelvis (eg, posterior and anterior cul-de-sac, uterosacral ligaments, tubes, ovaries), but any organ system is potentially at risk (see the following images).These ectopic foci respond to cyclic hormonal fluctuations in much the...

Endometriosis (en-doe-me-tree-O-sis) is an often painful disorder in which tissue similar to the tissue that normally lines the inside of your uterus - the endometrium - grows outside your uterus. Endometriosis most commonly involves your ovaries, fallopian tubes and the tissue lining your pelvis. Rarely, endometrial tissue may spread...

Endometriosis is defined as the presence of endometrial glands and stroma outside the endometrial cavity and uterine musculature. Surgical appearance varies significantly from superficial blebs to infiltrating fibrosis. Direct visualization confirmed by histological examination remains essential for diagnosis.

Endometriosis, disorder of the female reproductive system characterized by the growth of endometrial tissue (uterine lining) in an abnormal location. Rather than flowing out of the uterus by way of the vagina (during menstruation), some fragments of the endometrium may leave via the fallopian tubes...
