Gastric carcinoids in a patient with pernicious anemia and familial adenomatous polyposis.

Familial adenomatous polyposis (FAP) is associated with upper gastrointestinal adenomas and adenocarcinomas. A carcinoid tumor in the base of a duodenal adenoma in a patient with FAP was documented only once before. We report a patient with FAP who has multiple gastric carcinoids plus pernicious anemia as a coexisting disease. Genetic analysis and studies of other FAP patients are necessary to establish whether an association exists between FAP and carcinoid tumors. Optimal management of this type of gastric carcinoid is uncertain.
