Tumor del estroma gastrointestinal de duodeno / Duodenal gastrointestinal stromal tumors (GIST)

RESUMEN

Los tumores del estroma gastrointestinal, son tumores mesenquimales, fusiformes o epitelioides, primarios del tracto digestivo, que comparten similitudes inmunofenotípicas con las células intersticiales de Cajal, localizadas alrededor del plexo mientérico. El pronóstico presenta cierta asociación con la localización anatómica, con tendencia a ser de mayor malignidad los localizados en intestino delgado. Presentamos el caso de un varón de 54 años con un tumor del estroma gastrointestinal de 2da. porción de duodeno, operado con buena evolución después de 6 meses(AU)

ABSTRACT

Gastrointestinal stromal tumors (GIST) are primary mesenchymal, either fusiform or epitheloid, tumors of the digestive tract that have immune phenotypic similarities to Cajal's cells located around the myenteric plexus. Prognosis is associated to certain extent to the anatomic location, being more malignant those located in the small bowel as a general tendency. Here is the case of a 54 years-old man with a gastrointestinal stromal tumor on the second portion of the duodenum; he was operated on and after six months, his progress is satisfactory(AU)
