Gastric duplication cyst causing hypergastrinemia in an infant

JPGN Reports, EarlyView.
Abstract Gastric duplication cysts are rare congenital anomalies, with fewer than 10% occurring in the stomach. We report a 14‐month‐old girl presenting with failure to thrive, recurrent emesis, hematemesis, and severe duodenitis with ulceration. Laboratory evaluation revealed marked hypergastrinemia (1781 pg/mL), and initial imaging was unrevealing ...

Clinical Outcomes of Antrectomy for Patients With Multiple Type I Gastric Neuroendocrine Tumors: A Case Series

DEN Open, Volume 7, Issue 1, April 2027.
Type I gastric neuroendocrine tumors (T1‑GNETs) often present as multiple lesions, complicating treatment. This retrospective case series study evaluates antrectomy outcomes in eight patients with persistent multiple T1‑GNETs during 2005–2023. Following antrectomy, tumor regression was observed in two patients and complete disappearance in six, with ...

Characteristics, management, and outcomes of patients with VIPoma–A retrospective analysis of the ENETS database

Journal of Neuroendocrinology, Volume 38, Issue 7, July 2026.
Abstract Introduction: VIPoma is an extremely rare functioning pancreatic neuroendocrine tumor. Therefore, data regarding treatment and outcome are very limited. Aim (s): This multicenter study aimed to analyze clinical characteristics, real‐world management, and outcomes of patients with VIPoma.

Massive gastrointestinal bleed due to multiple gastric neuroendocrine tumors

Journal of Digestive Endoscopy, 2015
Gastric neuroendocrine tumors (G-NETs) are uncommon lesions which are usually diagnosed on histological evaluation of gastric polyps. These may occur sporadically or due to hypergastrinemia in the setting of atrophic gastritis or Zollinger-Ellison ...

Neuroendocrine tumours through an epigenetic lens: Emerging insights for diagnosis and treatment

Journal of Neuroendocrinology, Volume 38, Issue 6, June 2026.
Abstract Neuroendocrine tumours (NETs) are well‐differentiated epithelial neuroendocrine neoplasms that frequently develop in the small intestine, pancreas, and lungs. NETs originate from neuroendocrine cells specialized in hormone secretion implicated in a number of physiological processes.

Endoscopic Ultrasound for the Management of Pancreatic Neuroendocrine Tumors: Diagnosis, Treatment, and Future Perspectives

Journal of Gastroenterology and Hepatology, Volume 41, Issue 4, Page 1173-1190, April 2026.
ABSTRACT Pancreatic neuroendocrine tumors (PanNETs) are increasingly diagnosed, reflecting greater clinical awareness, improved imaging, and revised classification. This review summarizes evidence on epidemiology, diagnostic workup, and endoscopic ultrasound (EUS)–guided management of PanNETs, encompassing diagnostic evaluation, tissue acquisition, and

Psychosocial Outcomes in Patients With Endocrine Tumor Syndromes: A Systematic Review

Pediatric Blood &Cancer, Volume 73, Issue 3, March 2026.
ABSTRACT Introduction The combination of disease manifestations, the familial burden, and varying penetrance of endocrine tumor syndromes (ETSs) is unique. This review aimed to portray and summarize available data on psychosocial outcomes in patients with ETSs and explore gaps and opportunities for future research and care.

Clinical Implications of Ki‐67 Index, Grade and Hormonal Changes in Pancreatic Neuroendocrine Tumors: Insights Into Tumor Heterogeneity Based on Primary and Secondary Lesions

Journal of Hepato-Biliary-Pancreatic Sciences, Volume 33, Issue 2, Page 141-150, February 2026.
In this retrospective study of metastatic and recurrent pancreatic neuroendocrine tumors, Murakami and colleagues demonstrated frequent discordance in Ki‐67 index and World Health Organization grade between primary and secondary lesions. Increased proliferation did not compromise survival, likely reflecting treatment adaptation. Rare hormonal phenotype

Synchronous Peripancreatic Lymph Node Gastrinoma and Gastric Neuroendocrine Tumor Type 2 [PDF]

Clinical Endoscopy, 2016
A 34-year-old man was referred to our hospital with gastric polypoid lesions and biopsy-confirmed neuroendocrine tumor (NET). Computed tomography (CT) revealed a 3×3.5×8-cm retroperitoneal mass behind the pancreas, with multiple hepatic metastases.
