Successful Endoscopic Management of Oxyntic Gland Adenoma: A Case Report

Oxyntic gland adenomas (OGAs) are benign gastric neoplasms composed of gland-forming epithelial cells with predominantly chief cell differentiation resembling oxyntic glands confined to the mucosa. If the tumor has submucosal invasion, it should be classified as gastric adenocarcinoma of fundic gland type. The OGAs can pose a diagnostic challenge, as they can resemble aggressive gastric neoplasms. There are no current guidelines on the management of OGA. Due to the relatively small size and low malignant potential, these lesions are typically managed endoscopically. In this case, we are reporting a 22-year-old woman who was diagnosed with OGA during evaluation of iron deficiency anemia and underwent successful endoscopic resection.
