Solitary Peutz-Jeghers Polyp of the Colon / 대한소화기내시경학회지

ABSTRACT

Peutz-Jeghers syndrome is an autosomal-dominant inherited disorder characterized by polyposis of the alimentary tract, the abnormal mucocutaneous pigmentation, and family history of Peutz-Jeghers syndrome. A single Peutz-Jeghers polyp arising in a patient without pigmentation and family history of Peutz-Jeghers syndrome is termed a solitary or isolated hamartomatous polyp of Peutz-Jeghers type. These solitary polyps are found most frequently in the small intestine but also occur in the large bowel and stomach as well. In a healthy 48-year-old man, a single large polyp was found incidentally in the ascending colon during colonoscopy and treated by snare polypectomy. Microscopic exam of the resected specimen revealed the features of hamartomatous polyp of Peutz-Jeghers type. There was no evidence of other polyps on esophagogastroduodenoscopy and small bowel series. We report a patient with solitary Peutz-Jeghers polyp of the colon, who had no stigmata associated with Peutz-Jeghers syndrome.
