The most common histologic types of uterine sarcomas are:
- Carcinosarcoma (mixed
mesodermal sarcomas [50%]).
- Leiomyosarcoma (30%).
- Endometrial stromal
The new uterine neoplasm classification of the International Society of
Gynecologic Pathologists uses the term carcinosarcoma for all primary uterine
neoplasms containing malignant elements of both epithelial and stromal light
microscopic appearances, regardless of whether malignant heterologous
elements are present.
