A 22-year-old patient
presents for a colonoscopy to confirm a diagnosis of Crohn's disease or
ulcerative colitis. He has been suffering from crampy abdominal pain with
watery diarrhea with admixture of blood and mucus for several weeks. During the
endoscopy, a typical picture of mucosal damage by these autoimmune
inflammations is described and a biopsy is taken for histological examination,
which finally establishes the diagnosis of ulcerative colitis. Ulcerative
colitis is a rare autoimmune type of inflammation of the digestive system that typically affects the mucosa and submucosa of
the rectum and colon. Which of the descriptions offered describes the normal
appearance of the colonic mucosa?
