Introduction: GS is often composed of myeloblasts with or without signs of maturation of promyelocytes and mesangocytes. The organizational structure is partially or completely destroyed. GS can occur in various parts of the body but gastrointestinal involvement is rare. Case presentation: An 11-year-old male patient presented with symptoms of systemic blood stasis, fatigue, and abdominal pain as the first symptom. He was diagnosed with acute myeloid leukemia. After treatment, the symptoms were relieved and abdominal pain disappeared. After 9 months, the patient developed abdominal pain again, and was diagnosed as gastric granulocytic sarcoma by ultrasound gastroscopy, pathological examination and immunohistochemical staining. Conclusion: For patients with AML, whether in the early diagnosis or during the course of chemotherapy, abdominal symptoms should be routinely checked for B-ultrasound and CT. If necessary, gastroscopy and pathological biopsy should be performed to avoid GS misdiagnosis.
