Adenomyosis is a medical condition characterized by the growth of cells that build up the inside of the uterus (endometrium) atypically located within the cells that put up the uterine wall (myometrium), as a result, a thickening of the uterus occurs. Endometrial tissue, besides from being misplaced in patients with this condition, it is completely functional. The tissue thickens, sheds and bleeds during every menstrual cycle.

Adenomyosis can be found together with endometriosis, however, patients with endometriosis present endometrial tissue abnormally located entirely outside the uterus. The two conditions are found together in many cases, but often occur separately. Before being recognized as a distinct condition, adenomyosis was called endometriosis interna. The less-commonly-used term adenomyometritis is a more specific name for the condition, specifying involvement of the uterus.

The condition is typically found in women between the ages of 35 and 50, but also affects younger women. Patients with adenomyosis often present with painful menses (dysmenorrhea), profuse menses (menorrhagia), or both. Other possible symptoms are pain during sexual intercourse (dyspareunia), chronic pelvic pain and irritation of the urinary bladder.

Adenomyosis may involve the uterus focally, creating an adenomyoma. With diffuse involvement, the uterus becomes bulky and heavier.

Adenomyosis is a gynecologic medical condition characterized by the abnormal presence of endometrial tissue (the inner lining of the uterus) within the myometrium (the thick, muscular layer of the uterus). When endometrial tissue is present abnormally entirely outside the uterus, it is considered to be a similar but distinct medical condition, endometriosis. The two conditions are found together in many cases, but often occur separately. Before being recognized as a distinct condition, adenomyosis was called endometriosis interna. The less-commonly-used term "adenomyometritis" is a more specific name for the condition, specifying involvement of the uterus.

The condition is typically found in women between the ages of 35 and 50, but also affects younger women. Patients with adenomyosis often present with painful menses (dysmenorrhea), profuse menses (menorrhagia), or both.

In adenomyosis, basal endometrium penetrates into hyperplastic myometrial fibers. Therefore, unlike functional layer, basal layer does not undergo typical cyclic changes with menstrual cycle.
