Colitis, plural colitides, is an inflammatory process that involves the colon.
Proctitis and cecitis redirect to this article, as the mucosa of the rectum and cecum are very similar to that of the colon.
Type of colitis
Infectious:
- Infectious colitis, not otherwise specified.
- C. difficle colitis (pseudomembranous colitis often used as a synonym).
- Cytomegalovirus colitis.
Idiopathic:
- Ulcerative colitis.
- Crohn's disease with involvement of the colon.
- Microscopic colitis.
Iatrogenic:
Ischemic:
Miscellaneous:
Grading colitis
"A grading scheme":†

Rectum, Biopsy:
- Mild active proctitis with minimal architectural changes.
- NEGATIVE for dysplasia.

Alternate comment
The inflammation is nonspecific; it could be due to infection, inflammatory bowel disease, ischemia, inflammation secondary to diverticular disease or therapy/drugs. Clinical correlation is required.
