What are the classifications of uterine fibroids?

There are different types of uterine fibroids, so if you want to treat them effectively, you need to treat them symptomatically according to their type. The classification of uterine fibroids includes intramural fibroids, subserosal fibroids, and submucosal fibroids, so you need to treat them symptomatically.

① Intramural myoma: Intramural myoma is also called intramyometrial myoma. The myoma is located in the myometrium and is surrounded by normal myometrium. The boundary between the myoma and the myometrium is clear. The uterine muscle wall squeezed around the myoma is often called a pseudocapsule. This type of myoma is the most common, accounting for 60% to 70% of the total number of myomas. Myomas are often single or multiple, of different sizes. Small ones are as big as rice grains or soybeans and do not change the shape of the uterus. Large ones can enlarge the uterus or change the shape of the uterus into irregular protrusions, and the uterine cavity is often deformed accordingly.

③Submucosal fibroids: Submucosal fibroids are intramural fibroids close to the uterine cavity, growing toward the uterine cavity, and covered with endometrium on the surface. They are called submucosal fibroids. This type of fibroid protrudes from the uterine cavity and can change the shape of the uterine cavity. Some fibroids are only connected to the uterine wall by a pedicle, which is called a pedunculated submucosal fibroid. This type of fibroid is like a foreign body in the uterine cavity, causing reflex uterine contraction. Due to gravity, the fibroid gradually moves downward to the internal os of the cervix, and eventually the pedicle is elongated, and the fibroid is gradually pushed to the external os of the cervix or the vaginal opening. This type of fibroid accounts for about 10% of the total. Since the fibroids are located in the uterine cavity, the uterus mostly grows consistently. Due to the traction of the fibroids and insufficient blood supply to the fibroid pedicles, the uterus may have mild inversion and bleeding, necrosis, and infection of the endometrium on the surface of the fibroids, causing irregular vaginal bleeding and increased secretions. There are often multiple uterine fibroids, and two or even three of the above-mentioned fibroids may occur simultaneously in the same uterus, which is called multiple uterine fibroids.
