Abstract: InTRODUÇÃOOs tumores do estroma gastrointestinal (GISTs) ocorrem predominantemente de forma esporádica e representam cerca de 1% de todas as neoplasias do trato gastrointestinal 12 . As evidências atuais apontam que a origem dos GISTs tem relação direta com as células intersticiais de Cajal, as quais fazem parte do plexo mioentérico do trato digestivo e são responsáveis pelo controle da motilidade intestinal 9 . Em geral os GISTs são neoplasias bem delimitadas que se projetam exofiticamente em direção à luz do… Show more
