Abstract A 60‐year‐old woman presented with a protruding tumor at the anterior wall of the middle gastric body, and she was positive for anti‐parietal cells antibodies with elevated serum gastrin level. Final diagnosis was a mixed neuroendocrine–non‐neuroendocrine neoplasm consisting of adenocarcinoma (tub1) and neuroendocrine tumor G2 with autoimmune gastritis.
