title: Intussusception of the appendix induced by sessile serrated adenoma: a case report.
abstract: Intussusception of the appendix vermiformis is a rare condition. It occurs     mainly in infants and children. Here, we report an intussusception case that     occurred in a 65-year-old male presenting with repeated periumbilical pain,     nausea, vomiting and febrile sensation. The appendix was seen to be     intussuscepted at laparoscopy. The invaginated segment was reducted and simple     appendicectomy was carried out. Histopathologic examination revealed a sessile     serrated adenoma at the wall of the appendix, suggesting it as the cause of the     intussusception.
