title: Primary malignant hemangioendothelioma of the gingiva. Report of a case and review of the literature.
abstract: Primary malignant tumors of vascular origin are exceedingly rare in the oral cavity. Consequently, knowledge of their clinical and pathologic features is scanty. The varied array of terms applied to malignant vascular tumors has only further confused the issue. This article presents a review of twenty examples of oral malignant vascular tumors, with a report of a single personally studied case. Specifically, this case presented as a soft-tissue gingival lesion which subsequently invaded bone and represents a malignant hemangioendothelioma.
