Where Does Endometriosis Grow?

Endometriosis has been found in every organ and anatomical structure in the body. However, the lower abdominal cavity (pelvic cavity) is the most common general area where endometriosis occurs, and the most common cites include the peritoneum (lining of the pelvic area), rectouterine pouch (also called the Pouch of Douglas or or cul-de-sac), rectovaginal septum, uterosacral ligaments, ovaries, fallopian tubes, all over the outside of the uterus, including underneath it and behind it, the appendix, bowel, bladder, and rectum. Meanwhile, adenomyosis, thought to be at least a cousin of endometriosis, if not simply another form of the disorder, occurs inside of the uterus, with the endometrial-like cells growing into the muscular wall of the uterus instead of outside of the uterus, like endometriosis does.

While less common, endometriosis can also grow in other areas, including on blood vessels, the cervix, diaphragm, lungs, nerves, ureters, vagina, and inside of cesarean or other surgical scars.

Rare cases of endometriosis
Although exceedingly rare, endometriosis can even invade other vital organs and structures such as the kidneys, the eyes, liver, pancreas, brain, bone, heart, skin, and nasal cavity.
