Epithelioid leiomyosarcoma of the uterus.
Uterine epithelioid leiomyosarcoma is an unusual smooth muscle neoplasm. It is distinguished on cytoarchitectural grounds from the majority of leiomyosarcomas that arise in the uterus. Three cases of this atypical lesion are presented and the pathologic features are discussed. One patient is alive with no evidence of disease at 3.5 years, one patient has persistent disease at 4 years, and the third patient died of disease at 8 months. Fundamental differences in biologic behavior of this subset of uterine smooth muscle tumors cannot be discerned.
