Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors that can originate in the digestive tract and are most common in the stomach. Typically accounting for only 0.1% to 3% of gastrointestinal tumors, approximately 10% to 30% are clinically malignant neoplasms. Case presentation: A 66-year-old female patient has a medical history of high blood pressure, cardiac arrhythmia and glaucoma; He was admitted as an emergency and underwent an upper gastrointestinal endoscopy, revealing signs of recent upper gastrointestinal bleeding and a probable pancreatic infiltrating proliferative lesion. 3 days after admission to the emergency room, an abdominal CT scan was performed where a large heterogeneous solid mass was identified. The patient underwent in bloc resection of the mass (pancreas, spleen and gastric portion). Histopathology of the excised specimen was consistent with a high- risk gastrointestinal stromal tumor of the stomach (positive for CD 117). Conclusion: Giant GISTs are rare. Surgical removal with curative intent is feasible; The patient must be studied well to determine resectability.
