ABSTRACT
RESUMEN: El linfoma extranodal de células T/NK es una neoplasia maligna agresiva que se caracteriza por una destrucción de estructuras de la línea media de la cara como paladar y fosa nasal. Presentamos el caso de un paciente de sexo masculino, 48 años de edad, consumidor de cocaína, que consulta en la Facultad de Odontología de la Universidad de Chile en Septiembre del 2015 por síntomas de disfagia, rinorrea y que presenta al examen clínico un tumor ulcerado que compromete paladar duro y blando, de un mes de evolución. Se confirma diagnóstico de linfoma de células T/NK con una batería de pruebas inmunohistoquímicas. Esta patología, aunque infrecuente, siempre debe ser considerada dentro los diagnósticos diferenciales en tumores ulcerados en esta localización.
ABSTRACT: Extranodal T / NK cell lymphoma is an aggressive malignant neoplasm characterized by destruction of midline structures of the face such as the palate and nasal fossa. We present the case of a male patient, 48 years old, cocaine user, who consults at the Faculty of Dentistry of the Universidad de Chile in September of 2015 due to symptoms of dysphagia, rhinorrhea and presenting to the clinical examination an ulcerated tumor which compromises hard and soft palate, a month of evolution. Diagnosis of T / NK cell lymphoma is confirmed with a battery of immunohistochemical tests. This pathology, although infrequent, should always be considered within the differential diagnoses in ulcerated tumors of this location.

Abstract: Extranodal NK/T-cell lymphoma nasal type is a rare disease that mainly affects the nasal cavity and paranasal sinuses of males in the fifth decade of life. It has aggressive and locally destructive behaviour, and can be complicated by the hemophagocytic syndrome, conferring high lethality to the disease. This article describes a case of NK/T-cell lymphoma nasal type in a previously healthy patient, exemplifying its rapid and fulminant course.

La infección por el virus de Epstein-Barr puede afectar de manera muy variada al ser humano en sus diferentes etapas de la vida. Algunas veces las manifestaciones son asintomáticas o con síntomas poco específicos y otras puede presentarse como una enfermedad de severidad y duración variable, que puede desarrollar un proceso maligno. Hasta el momento se ha estudiado muy poco sobre la relación del virus de Epstein-Barr y piel, por lo que se trata de hacer una revisión de esta enfermedad y sus diferentes expresiones en la piel.
Epstein-Barr virus infection can occur in different manners, affecting humans throughthe different stages of life. Sometimes, manifestations are asymptomatic or non specific;conversely it can occur as a disease of variable severity and duration, and occasionallyeventuate into malignancy. So far little has been studied on the relationship betweenEpstein-Barr virus and skin; therefore we present this review of the disease and its various expressions upon the skin.
