RESUMO
EBV-positive diffuse large B-cell lymphoma (DLBCL) in elderly is a new entity included provisionally in the most recent WHO Classification of lymphoid neoplasms. It usually affects elderly patients and has a poor survival. The goal of this report was to evaluate clinical, endoscopic characteristics and survival of five patients with this entity and gastrointestinal afectation. From five cases, three cases had gastric infiltration, one ileon and one in cecum.

Overall, lymphomas of the gastrointestinal tract are rare, although they are the most frequent extranodal location. The incidence of primary colic lymphoma, above all in the non-Hodgkin variant, is clearly higher in the HIV positive population, especially in subjects with AIDS. The authors present the case of a 51-year-old patient with AIDS undergoing antiviral therapy; he was suffering from abdominal pain and presented a palpable mass in the right iliac fossa; diagnosis was caecal non-Hodgkin lymphoma (NHL); radical right hemicolectomy was carried out with definitive histological diagnosis of Burkitt-type small cell NHL. The NHL of the colon represents no more than 1.2% of all malignant cancers of this part of the intestinal tract. Nevertheless such cases are comparatively frequent in patients with HIV virus, especially in the active phase and clinically proven to be due to immunodeficient syndrome. Of cardinal importance is the differential diagnosis between primary and secondary forms because of the different treatment and prognosis. Frequently such forms are observed in patients with AIDS, at advanced stages and with differentiated and hence more aggressive histotypes, also because they are present in organisms weakened by the underlying disease and by immunodeficiency. Primary NHLs of the colon are relatively frequent and aggressive in patients with AIDS; early diagnosis and treatment are therefore of fundamental importance to improve the oncological outcome for these patients.

El Linfoma de Células Grandes B difuso del anciano asociado al Epstein Barr es una nueva entidad incluida provisionalmente en la más reciente clasificación de neoplasias linfoides de la WHO. Usualmente afecta ancianos y tiene pobre sobrevida. El objetivo de este reporte fue evaluar las característica clínicas, endoscópicas y sobrevida de cinco pacientes portadores de esta entidad y compromiso gastrointestinal. Tres casos tuvieron infiltración gástrica y dos casos tuvieron compromiso del ileón y el ciego.
