[Intravascular leiomyomatosis of the uterus. Two cases and review of the literature].

We report two cases of intravenous leiomyomatosis, a rarely described benign tumor, which illustrate potential complications resulting from metastatic dissemination. Both cases were fortuitously discoveries. We discuss the diagnostic problems, etiological factors, therapeutic management and prognosis. Hysterectomy with bilateral salpingo-oophorectomy and regular follow-up with cardiac and pulmonary monitoring were performed. Pelvic pain disappeared and the patients are recurrence-free. The main difficulties concerned early diagnosis, complete resection and prognosis. These cases illustrate the importance of careful pathology examination of all uterine myoma resection specimens.
