We report here an intussusception of the appendix, the lead point being a villous adenoma, presenting in a 62-year-old male whose initial complaint was a progressive enlargement of a right inguinal hernia. The endoscopic, surgical, and pathologic data are presented. A review of the literature of this uncommon entity is also presented.
