ABSTRACT
Epithelioid Hemangioendothelioma (EH) is a vascular neoplasm of soft tissue, recently described by Weiss and Enzinger. The biologic al behavior of the tumor has a intermediate malignant potential, in the sense that it has an indolent course, with the potential for recurrence, but rarely metastasizes. This tumor arises from medium- to large-sized vessels, primarily involves the soft tissues of the extremities, as well as the liver, lung, and bone, and rarely occurs in the head and neck region. Only fifteen well--documented cases of Epithelioid Hemangioendothelioma involving the head and neck region have been reported. Nine cases have been recently reported in the oral cavity. This is a report of one additional case in the tongue. Because of the intermediate malignant potential of Epithelioid Hemangioendothelioma, complete tumor resection is recommended for intraoral lesions.

Malignant melanomas of the oral mucous membrane seems an infrequent pathology. They are characterized by a late diagnosis, bad prognosis and a disappointing treatment, because of the difficulties encountered for its total removal owing to complicated accessibility. We report one case of mucous membrane of the mouth in a 56 year-old man, diagnosed and operated in the General Hospital of Specialties "Ciudad de Jaen". The article end with a careful revision of the literature.
