Abstract：Objective To study the clinical manifestations and pathological features of neuroendocrine gastric carci-noma and gastric anaplastic carcinoma and reduce rates of misdiagnosis and mistreatment. Methods Retrospective analysis of the clinical data of neuroendocrine gastric carcinoma and gastric anaplastic carcinoma misdiagnosed as gastric malignant lym-phoma was carried out. Results In this report, the patient of case one was admitted for abdominal discomfort with black stool and weakness and the patient of case two was admitted for abdominal discomfort for two months. Gastric malignant lymphoma was suspected following gastroscopic and pathological detection of the two cases. The patients did not turn for better after treat-ment in department of hematology. The patients had gastrointestinal bleeding and anemia, then the patients underwent surgical treatment. Postoperative pathology confirmed neuroendocrine gastric carcinoma and gastric anaplastic carcinoma. Conclusion The clinical manifestations of neuroendocrine gastric carcinoma and gastric anaplastic carcinoma lack specificity and may easily be misdiagnosed as gastric malignant lymphoma. A thorough gastroscopic detection can help reduce misdiagnosis rate.
