intravenous leiomyomatosis

Intravenous leiomyomatosis (IVL) is a rare smooth-muscle proliferation that is of special interest because of its quasi-malignant behavior.

Intravascular leiomyomatosis (IVL) is characterized by the presence of smooth muscle in venous and lymphatic spaces within the myometrium.

Although the intravascular component usually consists solely of typical smooth muscle or variants of smooth muscle differentiation, some cases have been reported in which the intravascular component also included endometrioid glandular and stromal elements. The term "intravenous adenomyomatosis" to describe this unusual variant of IVL.
