WHO classification uterine sarcomas?

Uterine sarcomas have been classified into two categories: non-epithelial and mixed non-epithelial/epithelial malignancy, dependent on the tissue of origin. The distinction between uterine sarcomas and other uterine tumors is clinically difficult and is reliant on histological and imaging features.

What is the difference between a leiomyoma and a fibroid?

Uterine fibroids (also called leiomyomas) are growths made up of the muscle and connective tissue from the wall of the uterus. These growths are usually not cancerous (benign). Your uterus is an upside down pear-shaped organ in your pelvis. The normal size of your uterus is similar to a lemon.

What is uterine sarcoma?

What are uterine leiomyosarcoma and Uterine Carcinoma?

If the uterine muscle cell is the originator the tumor is a uterine leiomyosarcoma. Carcinosarcomas comprise both malignant epithelial and malignant sarcomatous components.
