Figure 3

(a) Fibromuscular obliteration by α-smooth muscle myosin observed around the pyloric glands in the background mucosa surrounding the lesion; in places, this extends as if to support the foveolar epithelium. (b) Inside the lesion, fibromuscular obliteration seems to support the foveolar epithelium. (c) Schema representing fibromuscular obliteration. Fibromuscular obliteration is surrounded by blue paint.
