BACKGROUND: Leiomyomatosis is a benign smooth muscle tumor which can provok e serious complications in case of intracaval or intracardiac extension. CASE REPORT: A 61-year-oid woman had undergone hysterectomy at the age of 4 5 years for a hemorrhagic fibroma, She underwent surgery for infiltrative b reast cancer 3 months before hospitalization and was taking tamoxifen 30 mg /day. In the cancer context, the diagnosis cavo-cardiac meta-static thrombu s was proposed but not confirmed at pathology. The diagnosis of uterine tis sue intravascular leiomyomatosis was established on the basis of pathology findings and immunohistochemistry results. DISCUSSION: Five other cases-of-leiomyomatosis after hysterectomy have been reported in the literature.
