What is gynecological adenomyosis?

What's the matter with nodules in the lungs? Do you know what disease it is? It is also a very common gynecological disease. This disease is located in the uterus, also called endometriosis, which is intrinsic. It is generally very common in women aged 30 to 50. So do you know what kind of disease this is? Let's take a look at what gynecological adenomyosis is.

Causes

Through serial section examination of adenomyosis specimens, it was found that some endometrial lesions in the myometrium were directly connected to the endometrium on the uterine cavity surface. Therefore, it is generally believed that trauma to the uterine wall during multiple pregnancies and childbirth and chronic endometritis may be the main causes of this disease. In addition, since there is a lack of submucosal layer under the basement membrane of the endometrium and adenomyosis is often accompanied by uterine fibroids and endometrial hyperplasia, some people believe that the invasion of the basal endometrium into the myometrium may be related to the stimulation of high estrogen.

pathology

The uterus usually enlarges uniformly but rarely exceeds the size of a 12-week gestational uterus. There are two types of intrauterine lesions: diffuse and localized. Generally, they grow diffusely and often involve the posterior wall, so the posterior wall is often thicker than the anterior wall. When the uterine wall is dissected, it can be seen that its muscle layer is significantly thickened and hard. There is no obvious and regular spiral structure seen in the cross section of the uterus. Only thick muscle fiber bands and microcystic cavities are seen in the muscle wall, and old blood can occasionally be seen in the cavity. A small number of endometrium grows locally in the myometrium to form nodules or masses, similar to intramural fibroids, which are called adenomyomas. The difference between adenomyoma and myoma is that there is no capsule around it, so there is no obvious boundary with the surrounding muscle layer, making it difficult to peel it out of the muscle layer. Microscopic examination revealed island-like distribution of endometrial glands and stroma within the myometrium. Since ectopic endometrial cells belong to the basal layer of the endometrium and are insensitive to ovarian hormones, especially progesterone, ectopic glands are often in the proliferative phase, and only occasionally secretory changes are seen in local areas.

Clinical manifestations and diagnosis

About 30% of patients do not have any clinical symptoms of adenomyosis. Any multiparous woman over 30 years old who experiences increased menstrual flow, prolonged menstrual periods, and progressive dysmenorrhea that worsens year by year, and whose uterus is uniformly enlarged or has localized nodular protrusions, is hard and tender, and the tenderness is particularly significant during menstruation, should first be considered as having adenomyosis. B-mode ultrasound examination can show irregular echo enhancement caused by the implanted endothelium in the muscular layer.

What is gynecological adenomyosis? The above introduction explains this disease in detail. We need to understand the causes of the disease. If female friends suffer from such a disease, don’t be anxious, don’t panic, and actively seek relevant scientific treatment.
