Figure 2 Hyperplastic polyp from the gastroesophageal junction was comprised of cardiac type mucosa with foveolar hyperplasia and cystic dilatation of gastric pits (HE x 100).

Figure 3 Sessile lesion arising in the Barrett’s esophagus: the adenomatous villous-type polyp is composed of low grade dysplastic epithelium (HE x 250).
