title: Duplicated appendix complicated by appendiceal cancer.
abstract: A 37-year old male presented with an acute abdomen suggestive of an appendiceal perforation. Urgent laparotomy showed a duplicated appendix with one of the lumens involved with appendicitis and a focal peri-appendicular abscess while the other lumen had a localized appendiceal cancer. Recognition of congenital intestinal duplications in adults is important to avoid serious clinical consequences.
