title: [Primary malignant hemangioendothelioma (angiosarcoma) of the uterus--report of two cases and review of literature].
abstract: Two patients with primary malignant hemangioendothelioma of the uterus are reported. Clinically, both patients had no specific symptoms. The tumor was diagnosed as leiomyoma of the uterus before operation but proved to be malignant hemangioendothelioma histopathologically. One patient, a 46-year-old woman with a well differentiated hemangioendothelioma who has been followed for 12 years after hysterectomy is still alive. The other patient, a 62-year-old woman, with poorly differentiated hemangioendothelioma, died of brain metastasis 4.5 years after simple resection of the tumor. Our observation showed that there was a relationship between the degree of differentiation of the tumor and its prognosis. Nine cases from the foreign literature were reviewed.
