title: Intraoral Masson's vegetant intravascular hemangioendothelioma.
abstract: Two cases of Masson's vegetant intravascular hemangioendothelioma are described. The intraoral appearance of these reported lesions are rare. Due to histologic similarities to angiosarcoma and the benign progression of vegetant intravascular hemangioendothelioma, a thorough discussion of these diseases is presented.
