What would you do next?
There are multiple, small 2-4mm, sessile polyps with a smooth surface throughout the entire stomach, mainly concentrated at the fundus and body upon retroflexion of the endoscope.
What is your differential diagnosis?
•Fundic gland polyp.
How would you proceed?

•Drug history — any long-term use of proton pump inhibitors.
The biopsy results show some dilated fundic glands lined by an attenuated layer of chief and parietal cells with no features of dysplasia or malignancy, in keeping with the diagnosis of fundic gland polyps.
