Definition

An infiltrating mesenchymal tumor arising from the uterine corpus, cervix, vagina, and the ovary. It is characterized by the presence of oval to spindle-shape cells that resemble the cells of the endometrial stroma, without evidence of significant atypia and pleomorphism. Numerous small vessels are also present. It is usually characterized by indolent growth and late recurrences. [from NCI]
