Coexistencia gist con cáncer gástrico

Abstract

Gastrointestinal stromal tumors (GIST) in conjunction with adenocarcinoma are rare, these constitute the majority of non-epithelial neoplasms of the stomach. They can compromise the small intestine, mesentery and retroperitoneum. Originates from the interstitial cells of Cajal, wall of the gastrointestinal tract and can be distinguished from other tumors by immunohistochemistry. Pathogenesis of gastric cancer is related to environmental factors. Its incidence has declined in countries like the US and Britain, but remains high in others such as Japan, Chile and Italy. There is evidence that genetic predisposition plays an important role in a subset of patients. Gastric carcinomas originate from the basal cells of the foveal on a background of chronic atrophic gastritis with progressive dysplasia. Meet one recorded case in Cuenca concomitant gastric adenocarcinoma and GIST, which corresponds to a 75-year-old spoke gastric intramucosal well differentiated adenocarcinoma, also during surgery the presence of a tumor in the jejunum is noted for study revealed the presence of pathological GIST confirmed with immunohistochemistry techniques.
