Ulcerative colitis primarily involves the mucosa and the submucosa, with the formation of crypt abscesses and mucosal ulceration. The mucosa typically appears granular and friable. In more severe cases, pseudopolyps form, consisting of areas of hyperplastic growth with swollen mucosa surrounded by inflamed mucosa with shallow ulcers. In severe ulcerative colitis, inflammation and necrosis can extend below the lamina propria to involve the submucosa and the circular and longitudinal muscles.
