Morphological and structural characteristics of uterine fibroids

Uterine fibroids are the most common benign tumors of the female genitals. Most patients are asymptomatic, so they are often ignored by women. In fact, if uterine fibroids are not treated in time, they can also cause female infertility or miscarriage; cause adnexitis, pelvic inflammatory disease; lead to secondary anemia; and cause malignant lesions, etc. By understanding the morphology and structure of uterine fibroids, patients can deepen their understanding to a certain extent and pay enough attention to it in their minds.

Uterine fibroids, also known as uterine leiomyoma, are solid tumors that can grow in any part of the uterus, either singly or in multiples, with a smooth or uneven surface. They vary greatly in size, with the largest weighing tens of kilograms and the smallest even having dozens or hundreds of them growing at the same time. Generally, small fibroids are spherical in shape, but when they grow larger or multiple fibroids fuse, they become irregular in shape.

The texture of uterine fibroids is harder than that of the uterus, and the presence of fibroids can be easily felt outside the uterus. Fibroids do not have capsules, and they compress the surrounding muscle wall fibers to form a pseudocapsule. The connection between the capsule and the fibroids is loose, and the boundary is clear, so it is easy to peel the fibroids from the muscle wall. There are radial blood vessels distributed in the capsule to supply nutrition to the fibroids. The larger the fibroids, the thicker the blood vessels and the more numerous they are. When the diameter of the fibroids exceeds 4cm, it is more likely to degenerate.

The surface of the tumor is light in color, and the cross-section is grayish white. A spiral or woven structure can be seen, which is closely arranged.
