Figure 1: Colonic biopsies of case 1: (a) Arrows denote a thickened subepithelial collage band. Arrow head denotes superficially predominate mononuclear cell infiltrate in the lamina propria and (b) At 1 year follow-up, please note the marked decrease in the cellular infiltrates and normal collagen thickness (H and E, ×200)
