Histopathologically, the mucosa of the large colon is hemorrhagic, necrotic and covered with fibrohemorrhagic exudate, while the submucosa, the muscular tunic and the local lymphonodes are edematous.

The submucosa of the colon is composed almost entirely of collagen, both type I and type III . Several layers of collagen fibres make up the submucosa of the human colon.

In 1999 the same team showed that the presence of a non-lifting sign correlated with the depth of invasion of the submucosa by early colorectal cancers that were being considered for endoscopic resection.

The submucosa contains nerves including the submucous plexus ( Meissner's plexus ), blood vessels and elastic fibres with collagen, that stretches with increased capacity but maintains the shape of the intestine.
26.
NETs are often small, yellow or tan masses, often located in the submucosa or more deeply intramurally, and they can be very firm due to an accompanying intense mitotic activity, and necrosis.

The Carbondale, Colorado, man is the first person to receive an implant of small-intestinal submucosa, or SIS, a paper-thin material derived from hogs'small intestines that has shown promise in regenerating damaged tissue.

ESD is characterized by three steps : injecting fluid into the submucosa to elevate the lesion from the muscle layer, circumferential cutting of the surrounding mucosa of the lesion, and subsequent dissection of the connective tissue of the submucosa beneath the lesion.

The tumours which did lift when fluid was injected were found to be less invasive than those that did not ( sm1 or sm2-invasion confined to the upper two thirds of the submucosa, with at least 1mm of uninvolved submucosa underneath ).
