At the far right, malignant glands invade the lower part of the lamina propria (hematoxylin-eosin, original magnification ×40). B, Higher magnification showing medium-sized glands with haphazard growth, composed of malignant cells with marked variation in nuclear size, disorderly arrangement of nuclei, irregular nuclear membranes (hematoxylin-eosin, original magnification ×400).
