Appendicitis epiploicae: a rare cause of acute abdomen.

Acute appendicitis is one of the most common causes of right lower quadrant acute abdominal pain in adults. Some other conditions, including appendicitis epiploicae, can simulate an acute abdomen. Appendicitis epiploicae or epiploic appendicitis usually originates in the sigmoid colon and rarely from other parts of colon. We report a case of a 20-year-old man with appendicitis epiploicae of the caecum, who underwent surgery for acute appendicitis. Analysis of this uncommon condition, together with a review of the pertinent literature, are presented.
