Small intestinal hamartomatous polyp due to Peutz-Jeghers syndrome in middle childhood.

Small-bowel surveillance is recommended from the age of 8 years in asymptomatic individuals with Peutz-Jeghers syndrome. Because intussusception and risk of strangulated ileus were noted in an 11-year-old patient, small-bowel surveillance should be reliably performed from the age of 8 years to avoid urgent surgery.
