 Carcinosarcomas, also known as malignant mixed Müllerian tumors (MMMT), are uncommon malignancies that demonstrate both epithelial (carcinomatous) and mesenchymal (sarcomatous) differentiation. While most carcinosarcomas arise in the uterus, they can also develop in the ovaries, fallopian tubes, cervix, and, very rarely, the female peritoneum. These tumors predominantly affect older postmenopausal individuals, with 90% of cases occurring in those over 50 years of age. MMMTs are classified as high-grade endometrial carcinomas and are characterized by both a carcinomatous and a sarcomatous component. Risk factors for MMMT include nulliparity, obesity, advanced age, exposure to exogenous estrogens, pelvic irradiation, and long-term use of tamoxifen. MMMTs are highly aggressive tumors with a poor prognosis, comprising only 1–2% of uterine neoplasms and responsible for 15% of deaths from uterine malignancy. MMMT is characterized by a carcinomatous and a sarcomatous component, and the s...
