Leiomyoma Epithelioid

Leiomyoma is a benign tumor that is formed from smooth muscle tissue and can be either malignant or benign. Leiomyoblastomas are a type of leiomyoma that have a more aggressive behavior and are more common in children and adolescents.

Epithelioid leiomyomas (EL) are the most common form of leiomyomas and account for about 80% of all leiomyomas. They are characterized by the presence of epithelial cells, which are usually located in the form of sheets or cords in the center of the tumor. These cells may be associated with blood vessels or lymph nodes.

ELs can occur anywhere in the body, but are most common in the uterus, ovaries, breasts, and lungs. In the uterus they can lead to the formation of fibroids, and in the ovaries they can lead to the formation of cysts.

Treatment for EL depends on the size of the tumor, its location, and the symptoms it causes. If the tumor is small and does not cause any symptoms, observation may be required. In some cases, surgical removal of the tumor may be required.

However, if the tumor is large or causes symptoms such as pain, bleeding or pressure on nearby organs, more radical treatment such as chemotherapy or radiation therapy may be required.

Overall, leiomyoma is a common disease that can be caused by various factors. However, thanks to modern treatment methods, most patients can live a long time without complications.

Leiomyomas are the most common tumors of the uterus, accounting for an average of 42% of all cases of malignant tumors of this organ. Such benign neoplasms have a second name - leiomyoblastoma. Every fifth patient with leiomyosarcoma is diagnosed over 50 years of age. Lymphoepithelioepithelial cancer usually occurs in women over 30-35 years of age; less commonly, it is diagnosed in patients aged 20 to 25 years (30%).
