title: Epithelioid angiosarcoma arising in uterine leiomyomas.
abstract: Primary angiosarcomas of the uterus are exceedingly rare. The authors report a unique case of this entity arising in connection with uterine leiomyomas. The malignant tumor cells showed focally epithelioid features and were immunoreactive for keratin. Electron microscopy and immunohistochemistry confirmed their endothelial nature.
