Abstract Background Peutz-Jeghers syndrome (PJS) is an unusual autosomal dominant disorder characterized by mucocutaneous pigmentation and multiple gastrointestinal hamartomatous polyps. Patients with PJS are at increased risk of developing multi-organ cancer, most frequently those involving the tract.
