MME and neoplasm: Immunohistochemistry indicated a phenotypic transition from a uterine leiomyosarcoma to a vaginal epithelioid lesion; marker expression changed from the uterine tumor actin+/desmin+/caldesmon+/CD10− phenotype, through the tumor emboli, to an actin−/desmin−/caldesmon−/CD10+ phenotype in the vaginal lesion.
