Overview
Peutz-Jeghers, also known as Hereditary Intestinal Polyposis Syndrome, is an autosomal dominant genetic disorder characterized by the appearance of multiple benign hamartomatous polyps in the gastrointestinal tract. It's also associated with hyperpigmented macules on the lips and oral mucosa (melanosis). The incidence of Peutz–Jeghers syndrome is approximately 1 in 25,000 to 300,000 births.
