A Case of Gastric Neuroendocrine Tumor With a Raspberry‐Like Appearance on the Background of Acid‐Suppressive Therapy‐Related Gastropathy

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT We report the case of a 52‐year old man who was referred to our institution after a routine health check identified an asymptomatic gastric polyp. The medical history of the patient included reflux esophagitis, for which he had been treated with vonoprazan 10 mg daily for 6 years after initially receiving proton pump inhibitors.

Small Hepatoid Variant of Solid Pseudopapillary Neoplasm of the Pancreas: A Unique Case With Long‐term Follow‐up

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Hepatoid tumors are rare neoplasms that arise outside the liver but exhibit morphological and immunophenotypic features resembling hepatocellular carcinoma. Although hepatoid differentiation sometimes occurs in pancreatic ductal adenocarcinoma, its occurrence in solid pseudopapillary neoplasm (SPN) is exceedingly rare.

Distinct Adenocarcinoma and Neuroendocrine Carcinoma Components (Suspected Mixed Neuroendocrine‐Non‐Neuroendocrine Neoplasm) Identified by Targeted Biopsy Based on Differences in Endoscopic Findings in an Esophagogastric Junction Carcinoma: A Case Report

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Mixed neuroendocrine‐non‐neuroendocrine neoplasm (MiNEN) is a rare, highly malignant tumor comprising both neuroendocrine neoplasm (NEN) and non‐neuroendocrine neoplasm (non‐NEN) components. MiNEN arising at the esophagogastric junction (EGJ) is uncommon, and pretreatment identification of both components remains challenging.
