Although the latter two categories are rarely encountered, they tend to behave more aggressively and contribute to a disproportionately higher number of uterine cancer deaths. Pure sarcomas differentiate toward smooth muscle (leiomyosarcoma) or toward endometrial stroma (endometrial stromal tumors). Carcinosarcomas are mixed tumors demonstrating both epithelial and stromal components. These have also been known as malignant mixed müllerian tumor (MMMT). In general, uterine sarcomas and carcinosarcomas grow quickly, lymphatic or hematogenous spread occurs early, and the overall prognosis is poor. However, there are several notable exceptions among these tumors.
