title: Duodenal involvement in Gardner's syndrome.
abstract: It is suggested that duodenal polyps are more frequent in Gardner's syndrome than previously recognized. The polyps have a particular tendency to undergo malignant change. Two patients with Gardner's syndrome are reported in whom duodenal polyps were associated in one patient with periampullary cancer and in the other with a possible adenocarcinoma of the duodenum.
