Uncommon occurrence of intussusception in patient with Peutz-Jeghers Syndrome: Case report

UK: A recent case study published in the New England Journal of Medicine describes the case of a 26-year-old woman with Peutz-Jeghers syndrome who developed gastrogastric intussusception -- an uncommon but serious complication of the Peutz-Jeghers syndrome. 

Intussusception is a condition in which one intestine segment "telescopes" inside of another resulting in intestinal obstruction (blockage). It usually occurs at the junction of the small and large intestines and can cause swelling and inflammation leading to intestinal injury. 

Peutz-Jeghers syndrome is an inherited condition that predisposes a person to an increased risk of developing hamartomatous polyps in the digestive tract and cancer. PJS is caused by inheriting a mutation in the STK11 gene, also known as the LKB1 gene. 

The case in question is of a 26-year-old woman with a known history of the Peutz–Jeghers syndrome who was presented to the emergency department with a 1-week history of abdominal pain and nonbilious vomiting. The heart rate was 110 beats per minute, and the blood pressure 120/90 mm Hg. On examination, a tender mass was palpable in the upper abdomen.
