A case of malignant hemangioendothelioma (angiosarcoma) of the submaxillary salivary gland is reported and its microscopic and ultrastructural features are described and compared to previous reports of angiosarcoma arising in other locations. These tumors may often contain areas of solid sheets of cells without vascular characteristics and may be confused with poorly differentiated carcinoma or other sarcomas. The ultrastructural features of angiosarcoma are compared to other poorly differentiated tumors. It is concluded that the ultrastructural features of angiosarcoma are distinctive and aid in the diagnosis of this neoplasm.
