Who is at risk for ampullary and nonampullary duodenal adenomas?
- Ampullary and nonampullary duodenal adenomas can occur sporadically or in association with genetic syndromes such as familial adenomatous polyposis (FAP) or Peutz-Jeghers syndrome (PJS).
- Ampullary adenomas are considered premalignant lesions that can be treated surgically or endoscopically.
- Nonampullary duodenal adenomas have the potential for malignant transformation and are usually removed endoscopically.
