[Intravascular leiomyomatosis of uterine origin. a case of pseudo-metastatic cavo-cardial thrombus].
BACKGROUND
Leiomyomatosis is a benign smooth muscle tumor which can provoke serious complications in case of intracaval or intracardiac extension.


METHODS
A 61-year-old woman had undergone hysterectomy at the age of 45 years for a hemorrhagic fibroma. She underwent surgery for infiltrative breast cancer 3 months before hospitalization and was taking tamoxifen 30 mg/day. In the cancer context, the diagnosis of cavo-cardiac metastatic thrombus was proposed but not confirmed at pathology. The diagnosis of uterine tissue intravascular leiomyomatosis was established on the basis of pathology findings and immunohistochemistry results.


CONCLUSIONS
Five other cases of leiomyomatosis after hysterectomy have been reported in the literature.
