title: [Peutz-Jeghers syndrome: variability of gastrointestinal expression at pediatric age].
abstract: Peutz-Jeghers syndrome is a rare autosomal dominant condition, characterized by gastrointestinal polyposis, mucocutaneous pigmentation and high risk of neoplasia in multiple organs. At pediatric age, major clinical impact is related to complications associated to intestinal polyps, but neoplasic risk isn't negligible. Though clinical surveillance is recommended since the age of 10 years, relevant lesions may occur before that age. Conventional radiology and endoscopy have recognized limitations at this age group, and new diagnostic and intervention tools, such as video-capsule and per-operative enteroscopy, are not yet widely used. We present 5 pediatric cases (age under 10 years) with diversity of gastrointestinal expression (including one case with histologic evidence of dysplasia in a large colonic polyp), emphasizing the need of specific guidelines concerning young children.
