Gastrointestinal stromal tumors are mesenchymal tumors that represent 0.1% to 0.3% of all malignant tumors. Their clinical presentation is nonspecific but presentation by massive hemorrhage with hemodynamic instability is rare. We report the cases of 02 young patients who presented a fulminant digestive hemorrhage with hemodynamic instability and whose endoscopic exploration did not reveal any obvious etiology. That’s why we involved interventional radiology and surgical team in order to localize and confirm the diagnosis of a hemorrhagic jejunal GIST and then to ensure the hemostasis by small bowel resection taking away the jejunal tumor.
