title: Recurrent abdominal pain in 52-year-old male.
abstract: Key Clinical Message Intussusception of the appendix is a rare condition. Symptoms vary widely, whereas some patients are asymptomatic. Diagnosis is generally challenging and few cases have been diagnosed by colonoscopy. It is important to recognize the endoscopic appearance of this entity in order to avoid the potential hazard of an inadvertent "polypectomy".
