Gastric JP and duodenal JP in JPS patients. Large gastric JP (A–C) often shows a smooth surface contour with abundant edematous and inflamed lamina propria. The foveolar epithelium is hyperplastic and dilated forming cystic spaces. Infrequently, gastric JP may also have club-shaped or irregular villiform structures (D). Erosion and reactive epithelial changes are frequent. Duodenal JP observed in this study (E and F) is lined by small intestinal epithelium with abundant edematous and inflamed lamina propria and focal or diffuse gastric mucin cell metaplasia.
