A rare case of synchronous colocolic intussusception in association with Peutz-Jeghers syndrome.

Adult intussusception is rare and is almost always associated with a lead point. Polyposis syndromes are a common cause of adult intussusceptions, with polyps acting as lead points. Peutz-Jeghers syndrome is associated with benign hamartomatous polyps and mucocutaneous pigmentation. Although hamartomatous polyps are not premalignant, there is an increased risk of gastrointestinal and non-gastrointestinal malignancy, most commonly involving the small bowel. Most patients with Peutz-Jeghers syndrome with acute abdomen are diagnosed to have intussusceptions, mostly of the enteroenteric type. Colocolic intussusceptions are rare in Peutz-Jeghers syndrome. To the best of our knowledge, synchronous colocolic intussusception in association with Peutz-Jeghers syndrome has not been previously reported. Here we present a case of malignant jejunal mass and synchronous colocolic intussusceptions in a patient with Peutz-Jeghers syndrome.
