collagenous colitis  a type of colitis of unknown etiology characterized by deposits of collagenous material beneath the epithelium of the colon, with crampy abdominal pain and watery diarrhea.

granulomatous colitis  transmural colitis with the formation of noncaseating granulomas.

ischemic colitis  acute vascular insufficiency of the colon, affecting the portion supplied by the inferior mesenteric artery; symptoms include pain at the left iliac fossa, bloody diarrhea, low-grade fever, and abdominal distention and tenderness.

mucous colitis  former name for irritable bowel syndrome.

regional colitis , segmental colitis transmural or granulomatous inflammatory disease of the colon; regional enteritis involving the colon. It may be associated with ulceration, strictures, or fistulas.

transmural colitis  inflammation of the full thickness of the bowel, rather than just mucosa and submucosa, usually with formation of noncaseating granulomas. It may be confined to the colon (segmentally or diffusely) or be associated with regional enteritis in the small intestine. Clinically, it may resemble ulcerative colitis, but with deeper ulcerations, stricture formation, and fistulas, particularly in the perineum.

ulcerative colitis  chronic ulceration in the colon, chiefly of the mucosa and submucosa, manifested by cramping abdominal pain, rectal bleeding, and loose discharges of blood, pus, and mucus with scanty fecal particles.
