(D) Villi with preserved epithelium (Grade 0). (E) Dilation in the lymphatic vessel (asterisk) and slight subepithelial vacuolization in some villi (arrow) without forming subepithelial space (Grade 1). (F and G) Villi with small subepithelial spaces (Grade 1). (H) Villi with large subepithelial spaces that exceed twice the enterocyte size (Grade 2).
