Ileocecal valve
Revision as of 20:25, 1 September 2012 by Michael (talk | contribs) (→Lipomatous ileocecal valve: tweak)
The ileocecal valve is the divider between the small bowel and cecum. It is seen by pathologist in some subtotal colectomies (e.g. right hemicoloectomies) and occasionally biopsied.
Lipomatous ileocecal valve
- AKA lipomatosis of the ileocecal valve
General
- The lesion should involve the valve circumferentially.
- True lipomas of the ileocecal have a capsule, are not circumferential and less common.[1]
Clinical:
- May be misdiagnosed as malignancy.[2]
- Reported to mimic Crohn's disease.[3]
Microscopic
Feature:
- Mature adipocytes.
- No capsule.[1]
DDx:
- Lipoma of the ileocecal valve - have a capsule.
Ileocecal tuberculosis
General
- Ileocecal region and jejunoileal region are the most commonly affected areas in gastrointestinal tuberculosis.[4][5][6]
Microscopic
- See Tuberculosis.
