This study reports the case of a female in her forties who had a history of successful Helicobacter pylori eradication. She had undergone an EGD procedure as part of an annual medical check-up. The results revealed a small, slightly reddish elevated lesion along with erosion in the posterior wall of the antrum. A biopsy sample revealed dense expansion caused by a signet-ring cell carcinoma in the proper mucosal layer of the erosion site as well as the surrounding area of elevation. The protrusion was considered to be caused by dense growth of the carcinoma, though the form of the lesion changed from flat to slightly depressed before ESD was performed. The possibility of a protruding type of mucosal signet-ring cell carcinoma should be considered in the stomach of patients post eradication.
