Gastric serrated adenoma.

A 51 years-old male with several family history of gastric cancer, who was studied one year before for dyspepsia. A new gastroscopy was done that objectified in the greater curvature, a sessile polyp with slightly depressed center and a villous crypt pattern with Narrow Band Imaging. The histopathology study shown a horizontalization of the basal glands and basal dysplasia, compatible with serrated adenoma.
