Tumeur stromale du mésentère: une cause inhabituelle d’une masse abdominale

Abstract: Les tumeurs stromales gastro-intestinales (GIST) sont les tumeurs mésenchymateuses les plus fréquentes du tractus digestif. Elles représentent une entité nosologique individualisée depuis la découverte de l'expression quasi-constante de la protéine c-Kit détectée par la coloration immunohistochimique de l'antigène CD117. Des tumeurs avec les mêmes caractéristiques morphologiques et immuno-phénotypiques peuvent rarement apparaître en dehors du tractus gastro-intestinal. Nous rapportons le cas d'une jeune patien… Show more

“…The GISTs are uncommon GI tumors that involve mostly the stomach (60-70%) followed by the small intestine (20-30%) [ 1 - 2 ]. Despite their rarity, these tumors are the most common GI mesenchymal tumors [ 1 ].…”

“…Symptoms occur in the majority of cases and are usually related to gastrointestinal bleeding and to adjacent organ compression by the tumor [ 1 , 5 ]. However, asymptomatic GISTs account for 10-30% of total cases, which is explained by their submucosal localization and nonaggressive behavior [ 1 - 2 ]. Computed tomography scan and endoscopy suggests the diagnosis, whereas endoscopic ultrasound and/or surgery offer a pathological confirmation through demonstration of positive KIT (CD117) or platelet- derived growth factor receptor alpha (PDGFRA) gene mutations [ 1 , 6 ].…”
