Sumario:BACKGROUND: Intussusception in pediatrics is widely documented and well described. On the basis of the literature, however, adult intussusception is a rare entity with a prevalence of from 1% to 5%. The majority of adult patients with intussusception have an underlying pathology that needs to be identified by performing a proper physical examination and a wide array of investigations. CASE PRESENTATION: We present a case of a 66-year-old African man who presented to our emergency department with a mass protruding per anus with obstipation. During laparotomy, we found that the sigmoid colon had intussuscepted into the rectum and out from the anus. Other abdominal viscera were normal and without any obvious mesenteric lymphadenopathy. Sigmoid colectomy and spectacle colostomy were performed. Grossly, the excised bowel looked normal, but the histologic results showed features of necrosis and chronic inflammation. CONCLUSION: While 70% to 90% of cases of adult intussusception have an identifiable cause or lesion, most pediatric intussusceptions are idiopathic. The presentation in an adult described herein was of an uncommon idiopathic type with no identifiable cause found on the basis of the history, physical examination, or histological findings.
