This syndrome was first reported by J. Peutz in 1921 and confirmed by H. Jeghers in 1949. Its main symptoms are gastrointestinal polyps, black-brown pigmentation on the hands, feet, and lips, and genetic burden. Polyps occur most frequently in the small intestine (70%), but can also occur in the stomach, duodenum, and large intestine. Polyps in the large intestine are prone to becoming cancerous. They can be single or multiple. Onset occurs in childhood, and pigmentation often precedes the development of polyps. Intussusception can occur, accompanied by abdominal pain and bloody stool, and bleeding from polyps can cause iron deficiency anemia.
