Rectal ulcer secondary to a fecal impaction due to pomegranate seed bezoar.

Fecal impaction is a mass of hardened and compacted stools that the patient can not evacuate spontaneously. It usually occurs in elderly patients disabled or institutionalized but cases have also been reported secondary to foreign bodies, bezoars, etc. The usual symptom is constipation, but overflow diarrhea can also occur. The diagnosis of fecal impaction is made with digital rectal examination. Most of the time, it can be removed manually.
