The patient presented in hemorrhagic shock and required rapid factor VIII replacement and surgical resection after endoscopic and radiologic interventions were unsuccessful. This case highlights the importance of multidisciplinary coordination and individualized management in life-threatening gastrointestinal stromal tumor bleeding complicated by coagulopathy.
