Although sarcomas 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). In general, uterine sarcomas grow quickly, hematogenous or lymphatic spread occurs early, and the overall prognosis is poor. However, there are several notable exceptions among these tumors.
