Abstract

Gastrointestinal stromal tumors (GISTs) are a rare group of mesenchymal tumors mainly occurring in the gastrointestinal tract. Previously, GISTs were classified as smooth muscle tumors also known as leiomyomas, leiomyosarcomas or leiomyoblastomas. However, since the advent of immunohistochemistry, GISTs have been diagnosed on the basis of the identification of c-kit-positive cells. We here report a case of stromal tumor of the small intestine in order to analyze it in the light of literature data and imaging results, which may suggest prebiopsy diagnosis as well as its therapeutic and prognostic peculiarities.

Les tumeurs stromales gastro-intestinales (GIST) sont un groupe rare de tumeurs mésenchymateuses, localisé principalement dans le tractus gastro-intestinal. Auparavant, les GIST étaient classées comme des tumeurs musculaires lisses appelées léiomyomes, léiomyosacromes ou léiomyoblastomes. Cependant, avec l'avènement de l'immunohistochimie, les GIST sont maintenant définis par l'identification de la positivité de c-Kit. Dans ce travail, nous rapportons un cas de tumeur stromale de l'intestin grêle et nous en discutons, à la lumière des données de la littérature, les résultats d'imagerie qui peuvent suggérer un diagnostic pré-biopsie, ainsi que les particularités thérapeutiques et pronostiques.
