What are the signs and symptoms of Peutz-Jeghers syndrome (PJS)?

Peutz-Jeghers syndrome is characterized by the development of growths called hamartomatous polyps in the gastrointestinal tract (particularly the stomach and intestines), and a greatly increased risk of developing certain types of cancer.[1][2]

Children with Peutz-Jeghers syndrome often develop small, dark blue to dark brown spots on the lips, around and inside the mouth, near the eyes and nostrils, and around the anus.[1][3] These spots may also occur on the hands and feet. They commonly appear during childhood and often fade as the person gets older. In addition, most people with Peutz-Jeghers syndrome develop multiple polyps in the stomach and intestines during childhood or adolescence. Polyps can cause medical problems such as recurrent bowel obstructions, chronic bleeding, and abdominal pain.[1]

People with Peutz-Jeghers syndrome have a high risk of developing cancer during their lifetimes. Cancers of the gastrointestinal tract, pancreas, cervix, ovary, and breast are among the most commonly reported tumors.[1][2]
