Gastric Foveolar‐Type Hyperplastic Polyp of the Duodenum With GNAS and KRAS Mutations: A Potential Precursor to Neoplasia

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT We report a gastric foveolar‐type hyperplastic polyp of the duodenum harboring mutations in the GNAS and KRAS genes. The lesion was incidentally detected during a routine upper gastrointestinal endoscopy in a man in his 50s. It appeared as a 10‐mm elevated lesion located at the superior duodenal angle.

Diagnostic Performance of Magnifying Endoscopy With Crystal Violet Staining for Superficial Non‐ampullary Duodenal Epithelial Tumors: A Single‐center Prospective Study

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives We previously reported a potential diagnostic algorithm for superficial non‐ampullary duodenal epithelial tumors (SNADETs) using white‐light magnifying endoscopy with crystal violet staining (ME‐CV). This study aimed to determine the diagnostic performance of the scheme and compare it with the conventional white‐light endoscopy (WLE)
