Concurrent Diagnosis of a Gastric Neuroendocrine Tumor and an Adjacent Adenoma: An Approach to Diagnosis and Management

Abstract

The incidence of gastric Neuroendocrine Tumors (NETs) has been rising with the increasing use of diagnostic gastroscopy. Correctly differentiating a NET from a gastric adenoma is essential prior to embarking on further endoscopic management. Both of these lesions have distinct characteristics that can be identified endoscopically. We report a case of a patient who presented with a concurrent diagnosis of a gastric NET and adenoma and contrast their respective appearances endoscopically and the experience with their subsequent endoscopic resections.
