Abstract
Peutz–Jeghers syndrome is a genetic disease characterized by the development of benign hamartomatous polyps in the gastrointestinal (GI) tract and macules on the lips and oral mucosa. The incidence rate is not clear.
GI symptoms include:
Bleeding, anemia, abdominal pain
More severe: intussusception, obstruction, infarct
Clinical signs and findings should include :
Characteristic “hamartoma” polyps are found in the small bowel (90 %) and colon (50 %)
Symptoms from polyps arise in 33 % of patients by age 10 years and 50 % by age 20 years
Mucocutaneous hyperpigmented macules that develop in early childhood
