    Peutz-Jeghers syndrome, a rare genetic disorder, presents with characteristic mucocutaneous pigmentation and gastrointestinal polyps. Early diagnosis and management are crucial for these pediatric cases.

    Area of Science:

    • Genetics
    • Pediatrics
    • Gastroenterology

    Background:

    • Peutz-Jeghers syndrome (PJS) is an autosomal dominant disorder.
    • PJS is characterized by hamartomatous polyps in the gastrointestinal tract and mucocutaneous melanin spots.

    Observation:

    • Two pediatric cases of PJS are presented: a 13-year-old female and an 8-year-old male.
    • The female patient exhibited pigmented macules and significant gastric/jejunal polyposis requiring surgery.
    • The male patient displayed melanosis and minor gastric polyps.

    Findings:

    • Pediatric Peutz-Jeghers syndrome can manifest with varying degrees of polyp burden and pigmentation.
    • Surgical intervention may be necessary for severe polyposis in PJS patients.

    Implications:

    • Highlights the importance of recognizing PJS in children presenting with mucocutaneous pigmentation.
    • Emphasizes the need for vigilant gastrointestinal surveillance in pediatric PJS cases.
    • Informs clinical management strategies for Peutz-Jeghers syndrome in young patients.
