BACKGROUND Gastrointestinal schwannomas(GIS)are rare neurogenic tumors arising from Schwann cells in the gastrointestinal tract.Studies on GIS are limited to small case reports or focus on specific tumor sites,undersc...
Gastric schwannomas are rare mesenchymal tumors of the gastrointestinal tract.They are usually misdiagnosed as other submucosal tumors preoperatively.Experience of the imaging features of gastric schwannomas is extrem...
AIM: To investigate the role of angiopoietin (Ang) -1, -2 and -4 and its receptors, Tie-1 and -2, in the growth and differentiation of gastrointestinal stromal tumors (GISTs).METHODS: Thirty GISTs, seventeen leiomyoma...
AIM: To investigate the role of vascular endothelial growth factor (VEGF/and its receptors VEGFR-1 and 2 in the growth and differentiation of gastrointestinal strornal tumors (GISTs). METHODS: Thirty-three GISTs,...
AIM: Gastrointestinal stromal tumors (GISTs) are rare. GISTs differ from other mesenchymal tumors of the gastrointestinal tract (e.g. leiornyomas and schwannomas). The purpose of this study was to investigate the...
