          Abstract

          El Linfoma MALT o también llamado Maltoma es una entidad clínica bien conocida descrita como un tipo de respuesta inmune basada en la interconexión de órganos mucosos distantes entre sí. Dicha entidad se ha relacionado claramente con la infección por H. pylori como ente bacteriano que estimula la respuesta inmunológica, corroborándose tal causalidad al erradicarse la bacteria y observar la regresión del tumor en su totalidad. A continuación presentamos el caso de masculino de 76 años a quien se le diagnóstica un Linfoma MALT de alto grado y posterior a recibir tratamiento se logra la regresión total del tumor, el cual bajo un seguimiento estricto a lo largo de 10 años se mantiene asintomático.

          Linfoma MALT or also Maltoma call is a clinical organization described well-known good like a type of immune response based on the interconnection of distant mucous organs to each other. This organization has been related clearly to the infection by H. pylori like bacterial being that stimulates the immunological answer, corroborating such causality when eradicating itself the bacterium and to observe the regression of the tumor in its totality. Next we presented/displayed the case of masculine of 76 years to that diagnostic him a Linfoma MALT of high later degree and to be received treatment is obtained the total regression of the tumor, which under a strict pursuit throughout 10 years stays asintomatic.

          Helicobacter pylori-associated gastritis and primary B-cell gastric lymphoma.

          Although lymphoid tissue is absent in normal gastric mucosa, primary lymphomas arise in the stomach and most of these recapitulate the features of mucosa-associated lymphoid tissue (MALT). Gastric lymphoid tissue is known to be acquired in response to local infection by Helicobacter pylori, and we have confirmed this in 450 patients with H pylori-associated gastritis of whom 125 showed mucosal lymphoid follicles. In 8 patients, B lymphocytes infiltrated epithelium, which is a feature characteristic of MALT. We also examined 110 cases of gastric MALT lymphoma and found H pylori infection in 101 of these (92%). We conclude that gastric MALT is acquired in H pylori infection and that this provides the necessary background in which MALT lymphoma might develop.
