Benign cecal ulcer.

Benign cecal ulceration, generally presenting as a right lower abdominal mass or lower gastrointestinal bleeding in older patients, is often associated with typhoid fever, cytomegalovirus, and ingestion of nonsteroidal anti-inflammatory drugs. Diagnosis is generally made during surgery, but conservative treatment often leads to complete healing. In elective patients, repeated X-ray examinations of the colon, especially with air contrast barium enema and colonoscopy, are recommended to distinguish benign cecal ulceration from a malignancy.
