"GI tract adenocarcinoma, although the polyps themselves are not premalignant"
"Due to the increased risk of malignancy, screening is generally recommended. Examples include annual mammography and contrast-enhanced breast MRI, beginning at 25 years of age; baseline CT/MR enterography at 8-10 years of age (and every 2-3 years from 18 years of age); MRCP or endoscopic US every 1-2 years beginning from 30-35 years of age 4."
"It is attributed to mutations in tumour suppressor genes, most commonly STK11 (70-94%) 4."

"multiple hamartomatous polyps, most commonly involving the small intestine (predominantly the jejunum), but also colon and stomach; mouth and oesophagus are spared"

"mucocutaneous melanin pigmentation involving the mouth, fingers and toes"
"Findings on clinical examination include mucocutaneous hyperpigmented macules of the nose, buccal mucosa, axilla, hands, feet and genitalia 4. A clinical diagnosis can be made following histopathological confirmation of typical Peutz-Jeghers syndrome morphology in 2 or more intestinal polyps or after any number of polyps or hyperpigmented macules (in a characteristic location) with a positive family history 4."
