Key Points about Peutz-Jeghers Syndrome

Definition: Peutz-Jeghers Syndrome (PJS) is a hereditary condition characterised by the development of benign polyps in the gastrointestinal tract and distinctive pigmented spots on the lips, mouth, hands, and feet. It increases the risk of certain cancers, especially gastrointestinal cancers.
Causes: PJS is caused by mutations in the STK11 gene (also known as LKB1), which is responsible for regulating cell growth. The syndrome is inherited in an autosomal dominant pattern.
Symptoms: The hallmark signs include pigmented spots on the skin and mucous membranes, typically present in childhood, and gastrointestinal polyps, which can lead to abdominal pain, bleeding, or bowel obstruction.
Diagnosis: Diagnosis is based on the clinical features, family history, and genetic testing to confirm mutations in the STK11 gene.
Management: Treatment focuses on regular surveillance for polyps and cancer prevention. Polyp removal (endoscopic or surgical) may be necessary to prevent complications. Screening for cancers, particularly of the gastrointestinal tract, is essential in management.
Complications: Patients are at a significantly increased risk of developing gastrointestinal and other cancers (e.g., pancreatic, breast, ovarian). Early detection and prevention are key to improving outcomes.
