Peutz-Jeghers syndrome is a rare autosomal dominant disorder in which multiple hamartomatous polyps are present in the gastrointestinal tract in association with distinctive mucocutaneous pigmentation. A single hamartomatous polyp arising in a patient without pigmentation or familial history of Peutz-Jeghers syndrome is termed a solitary Peutz-Jeghers polyp; such a case is rare and would result in a case report being presented even in other countries. We experienced two cases of a solitary Peutz-Jeghers polyp that developed in the rectum, and report the cases with a review of the literature.
