 Autoimmune gastritis(AIG), characterized by diffuse atrophy of the gastric corpus, is associated with gastric neuroendocrine tumors and gastric cancer. In AIG, severe mucosal atrophy can reduce visibility, making the detection of lesions difficult. We report a case of poorly differentiated advanced gastric cancer arising in the background of AIG. Although the lesion was recorded and observed frontally by a surveillance endoscopy, it was initially overlooked. A retrospective analysis using the AI-assisted endoscopy system “gastroAITM model-G2” successfully identified the lesion. Our case highlights the utility of AI in improving diagnostic accuracy and preventing missed lesions, suggesting the potential application of AI in real-time clinical practice.
