The differentiation of amebic colitis from inflammatory bowel disease on endoscopic mucosal biopsies.

Background: Intestinal amebiasis is one of the important differential diagnoses of Inflammatory Bowel Disorders in areas where it is highly prevalent.

Aim: Studies comparing the clinical, endoscopic and histological features of these disorders have never been done, so we undertook this study.

Materials And Methods: A retrospective study comparing mucosal biopsies of 14 consecutive cases of intestinal amebiasis with 14 cases of Ulcerative colitis and 12 cases of Crohn's disease.
