Atypical Peutz-Jeghers Syndrome Presenting With a Huge Jejunojejunal Intussusception in a Young Male: A Case Report.

Intussusception is considered one of the rare causes of intestinal obstruction in adults compared to pediatric patients. It usually presents with non-specific clinical manifestations ranging from mild recurrent abdominal pain to severe acute abdominal pain. The non-specificity of its symptoms makes it difficult to diagnose preoperatively. As 90% of adult intussusceptions are due to a pathological lead point, this prompts the underlying medical condition to be identified. We herein report a rare case of a 21-year-old male with atypical clinical features of Peutz-Jegher syndrome (PJS), presenting with jejunojejunal intussusception as a result of a hamartomatous intestinal polyp. A preliminary diagnosis of intussusception was made after an abdominal computed tomography (CT) scan and was confirmed intraoperatively. Postoperatively, the patient's condition improved steadily, and he was discharged with a referral to the gastroenterologist for further assessment.
