60 years old male was referred for the treatment of gastric adenoma on the anterior wall aspect of the gastric angle. After endoscopic resection of the gastric adenoma with low grade dysplasia, 5-10% turns out to be a cancer. Depressed morphology is one of the risk factors. So, I explained that there is a 20% risk of cancer to the patient.

Endoscopic resection was done and the final pathology was adenoma with low grade dysplasia.


ESD: Tubular adenoma with low grade dysplasia ;
1. Location : angle, anterior wall
2. Gross type : depressed
3. Size of adenoma : (1) longest diameter, 32 mm (2) vertical diameter, 18 mm
4. Resection margin : negative resection margins(N)
5. Associated finding: Gastritis cystica superficialis

In a patients with gastric adenoma, it is very difficult to guess which one is cancer.
