NCI Definition: An aggressive malignant tumor of the female reproductive system, affecting predominantly elderly menopausal women. The endometrium and ovary are the most common sites of tumor origin. Morphologically, it is a high grade tumor, composed of carcinomatous and sarcomatous elements. [1]

Malignant mixed mesodermal (mullerian) tumors most frequently harbor alterations in TP53, CCNE1, KRAS, PIK3CA, and CEBPA [2].

Most Commonly Altered Genes in Malignant Mixed Mesodermal (Mullerian) Tumor

TP53 Mutation, TP53 c.217-c.1178 Missense, TP53 Missense, TP53 Nonsense, and TP53 Frameshift are the most common alterations in malignant mixed mesodermal (mullerian) tumor [2].
