Intussusception in Peutz-Jeghers Syndrome: Management of Unusual Acute Abdominal Presentation.

Peutz-Jeghers syndrome (PJS) is an autosomal dominant familial hamartomatous polyposis syndrome characterized by multiple gastrointestinal hamartomatous polyps and mucocutaneous melanin pigmentation. We report two cases, with no family history, presenting as emergency, one with perforation peritonitis due to spontaneous bowel disruption and another with bowel gangrene due to severe bowel congestion secondary to intussusception. Histological examination showed features of hamartomatous polyposis; other clinical features in these patients were suggestive of the diagnosis of Peutz-Jeghers syndrome. Given the multitude of carcinoma that these patients are susceptible to, aggressive screening protocols are recommended. Close monitoring and follow-up are essential in PJS patients for the prevention of potential complications, early detection of related malignancies due their increased risk for both intestinal and extraintestinal malignancies.
