Figure 3: Colonic biopsies of case 2: (a) Prior to the treatment with prednisone; 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 decrease in the cellular infiltrates and reduction of the collagen thickness (H and E, ×200)
