[Intravascular uterine leiomyomatosis].

Intravascular (intravenous) leiomyomatosis is a rare uterine neoplasm. The unusual growth and extension of histologically benign smooth muscle tumors in vascular channels of uterus and pelvis are cardinal features of the disease. The course of the affection has been benign in the majority of the cases reported in the literature. Clinical and pathologic aspects are briefly evaluated in the context of an example of intravascular leiomyomatosis in a 30-year-old woman.
