Solitary hamartomatous polyp of the duodenum in the absence of familial polyposis.
A large hamartomatous polyp of the Peutz-Jegher type was discovered in the distal duodenum by endoscopy in a patient with occult gastrointestinal bleeding. There were no other polyps in the gastrointestinal tract and the patient lacked any stigmata associated with the familial polyposis syndromes. This is the second well-documented case of an isolated hamartomatous polyp of the Peutz-Jegher type in the small intestine occurring in the absence of familial polyposis.
