Abstract
Adenomyosis is a benign uterus disease in which the invasion of the endometrial glands and/or stroma within myometrium is found and usually appears between the ages of 40 and 50 years in women. There are several differences in their pathogenesis. The secondary dysmenorrhea and menorrhagia are the common symptoms. Ultrasound sonography, MRI, CA125, and histological examination can be helpful for the diagnosis of adenomyosis. The treatment of adenomyosis depends on the patient’s age, symptoms, and desire for future fertility, including medical treatment and surgical treatment.
