[The Peutz-Jeghers syndrome and intestinal invagination]

Peutz-Jeghers syndrome is a autosomal dominant disorder characterized by hamartomatous polyposis of the gastrointestinal tract and mucocutaneous melanin pigmentation. This condition can occur and cause symptoms at any age, but intestinal obstruction due to intussusception is a frequent complication. Two cases of this syndrome associated to intussusception are reported. Both patients were girls, 2 and 8 years old respectively and underwent surgical treatment.
