Figure 1: (a) A cross-section of a case of LAMN with a flat epithelium. The lamina propria under the epithelium has disappeared and is replaced by fibrous connective tissue (HE ×50). (b) LAMN covered by undulating epithelium, (HE ×25). (c) LAMN covered by villiform epithelium (HE ×50). (d) Hyperplastic polyp of appendix (HE ×50). (e) HE section of the serrated lesion. The lamina propria and muscularis mucosa are preserved. Dilatation at the bases of the crypts draws attention (HE ×25). (f) Complete loss of surface epithelium is a common artifact in LAMNs (HE ×25)
