A1 Martín-Masot, Rafael A1 Cardelo Autero, Nerea A1 Ortiz Pérez, Pilar A1 Torcuato Rubio, Encarnación A1 Vázquez Pedreño, Luis A1 Gallego Fernández, Carmen A1 Blasco-Alonso, Javier A1 Navas-López, Víctor Manuel AB Juvenile polyposis syndrome (JPS) is a rare disease with an autosomal dominant inheritance pattern characterized by the development of multiple hamartomatous polyps in the gastrointestinal tract. The most frequent signs and symptoms are recurrent abdominal pain, rectal bleeding, anemia, and iron deficiency. The treatment of JPS is symptomatic, requiring serial endoscopic polypectomies or intestinal resections in the most severe cases. We describe the clinical case of a patient with JPS with a childhood juvenile polyposis phenotype because of a mutation on the SMAD4 gene, who received treatment with sirolimus successfully.
