摘　　要：Introduction Gastrointestinal stromal tumors(GISTs)are neoplasms arising from mesenchymal cells localized into the muscularis propria of the gastrointestinal(GI)tract[1];5%of GISTs are extra-GISTs(EGISTs),as they differently originate from adipose tissue adjacent to the GI tract(omentum and mesentery)or from the pancreas[2].So far,both GISTs and EGISTs have been managed indistinctively by combining surgery,histopathological distinctive features,imaging,and molecular analysis.Moreover.
