Some cases of polypoid lesions arisen from the gastric mucosa just below a lower esophageal erosion. This lesion can have various sizes and shapes. It is known as a hyperplastic lesion associated with esophagitis or an inflammatory lesion. Sometimes only a polyp is found without an erosion. This polypoid lesion is often called as sentinel polyp and is usually considered to be a benign lesion. Here we report a case of a pseudomalignant erosion in which an inflammatory polyp at the esophagogastric junction was successfully removed by endoscopic submucosal dissection even though the polyp was initially mistaken for a squamous cell carcinoma.

Key Words: Inflammatory polyp, Pseudomalignant erosion
