  Fig. 3. (A, B) Histologic examination of duodenal mucosa. Amorphous pinkish material deposition in lamina propria of duodenal mucosa (A: hematoxylin and eosin stain [H&E], ×100; B: H&E, ×200). (C) Congo red stain shows the amorphous material with pale pink color (congo red stain, ×200) and (D) birefringence is not detected under polarized light (congo red stain, ×200).
