Abstract excerpt

Nonampullary duodenal neoplasms of gastric phenotype include pyloric gland adenoma, foveolar-type adenoma, and duodenal neoplasm of uncertain malignant potential. In addition, previously undesignated epithelial tumors have been observed in the duodenum. Their clinicopathological and molecular characteristics, as well as their pathologic classification, remain incompletely defined due to their rarity. In this...
