[Primary intraoral epithelioid hemangioendothelioma. Case report and review of the literature]. / Hemangioendotelioma epitelioide primario intraoral. Presentación de un caso y revisión de la literatura.

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.

[Traumatic cervical subcutaneous emphysema in children]. / Enfisema subcutáneo cervical traumático infantil.

Neck emphysema is an unusual pathology in childhood depending on several conditions. We report the case of a subcutaneous emphysema of the neck after an oropharyngeal injury in a child and take the advantage of the event in order to review the etiology and pathogeny of neck emphysema, because the otolaryngologist must know the differential diagnosis, face to the presence of air inside the neck, since the definitive treatment depends on is etiology.

[Schwannoma of the cervical sympathetic chain]. / Schwannoma de la cadena simpática cervical.

Schwannomas are benign tumors of neural source produced from Schwann cells, which are the constituents and the maintenance of myelin sheath of peripheral nerves. Parapharyngeal schwannoma are sporadic and vagus nerve the one more frequently giving raise to parapharyngeal schwannoma. Those originated in sympathetic neck chain are more rare. We inform about a parapharyngeal schwannoma case of the neck sympathetic chain and perform an analyse of clinic, diagnostical, histological and therapeutical characteristics of this so infrequent pathology.

El Hemangioendotelioma Epitelioide (HE) es una neoplasia vascular de tejidos blandos, descrita recientemente por Weiss y Enzinger. Su potencial maligno es intermedio, en el sentido de tener un curso indolente, posible recurrencia y raras metástasis. Se presenta a lo largo de los vasos, principalmente involucra los tejidos blandos de las extremidades, además de hígado, pulmón y hueso, siendo infrecuente en cabeza y cuello. Sólo se han descrito quince casos en cabeza y cuello. De éstos, recientemente se han descrito nueve casos en cavidad oral. Aportamos un caso adicional en lengua.Debido al moderado potencial maligno del hemangioendotelioma epitelioide se recomienda la resección completa de las lesiones intraorales (AU)

[Intra-parotid facial plexiform neurofibroma. Review of the literature]. / Neurofibroma plexiforme de nervio facial intraparotídeo. Revisión de la literatura.

It is being tumor developed from Schwann cells of peripheral nerves sheath. In its plexiform type it is a rare growth presenting solitary or in the context of von Recklinghausen's disease. The aim of this article is to present one plexiform neurofibroma localized in the parotid gland. At the same time we make a perusal on the literature of this kind of tumor.

[Primary malignant melanoma of the oral cavity. Report of a case. Review of the literature]. / Melanoma maligno primario de cavidad oral. A propósito de un caso. Revisión de la literatura.

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.

[Metastatic carcinoma of the parotid gland. Review of the literature. Report of two cases]. / Carcinoma metastásico en glándula parótida. Revisión de la literatura a propósito de dos casos.

The great majority of parotid gland tumours are benign. Metastatic malignant ones are scarce in number. The source of these metastasis are growths localized either in head and neck or distant tumours spreading on intra- or periparotid lymph nodes. Two cases of metastatic parotid growths diagnosed and treated last year are reported. Bibliographic review of the topic.
