uterine carcinosarcoma (MONDO_0006485) is a usually aggressive malignant neoplasm arising from the uterine corpus and less often the cervix. It is characterized by the presence of two components: a malignant epithelial component and a sarcomatous component. In the uterine corpus the epithelial component is usually glandular whereas in the cervix is usually non-glandular. Carcinosarcoma of the cervix, although it is aggressive, it may have a better prognosis compared to the uterine corpus carcinosarcoma. Also known as: carcinosarcoma of the uterus, malignant mixed mesodermal (Mullerian) tumor of the uterus, malignant mixed mesodermal (Mullerian) tumour of the uterus, malignant mixed mesodermal (Müllerian) tumor of the uterus, malignant mixed mesodermal (Müllerian) tumour of the uterus, mixed mullerian sarcoma of uterus, uterine malignant mixed mesodermal (Mullerian) tumor, uterine malignant mixed mesodermal (Mullerian) tumour.
