Figure 4
Sections of laterally spreading tumor-nongranular (LST-NG) type with different degrees of submucosal fibrosis. (a) F0: no fibrosis, honeycomb-like appearance throughout; (b) F1: mild fibrosis, intensity of staining was high in ≺50% of the sample; (c) F2: severe fibrosis, intensity of staining was high almost throughout (Masson’s trichrome stain, original magnification ×10).
