Jejunal intussusception and polyps with different types of malignant transformation in Peutz-Jeghers syndrome: Report of a case.

Intussusception and malignant polyps are complications of Peutz-Jeghers syndrome. Very few cases of intussusception combined with polyps with different types of malignant transformation in Peutz-Jeghers syndrome have been reported to date. In the present study, we describe a case of Peutz-Jeghers syndrome with jejunal intussusception and malignant hamartoma in the jejunum and descending colon, combined with mucinous adenocarcinoma in the sigmoid colon.
