Myometriosis is a form of endometriosis and is a common gynecological condition. When the endometrial glands and interstitium invade the myometrium, it is called myometriosis, or adenomyosis. If the endometrial glands invade the myometrium in a diffuse form, it is called adenomyosis, which is characterized by uniform enlargement of the uterus; if the invasion is localized and the myometrium is locally enlarged in a tumor-like manner, similar to uterine fibroids, it is called adenomyoma. In the case of adenomyoma, the mass is unbounded and fused with the myometrium and cannot be separated. In some women with adenomyosis, there is no obvious discomfort, but in some women, menstrual pain, increased menstrual flow, prolonged menstruation, incomplete dripping, enlarged uterus on gynecological examination, hard texture with pressure pain, and uneven echogenicity on ultrasound, which may be considered as adenomyosis. The treatment of myoglandular disease depends on the patient’s symptoms and age. If the symptoms are obvious, the dysmenorrhea is severe, the hysterectomy can be performed at an older age and there is no requirement for childbirth; if you are young, try to keep one ovary. In conclusion, myasthenia gravis is a common gynecological disease that often causes dysmenorrhea, heavy menstruation, and uniform enlargement of the uterus, and can be treated with medication or surgery.
