Brunner’s Gland Adenoma: An Unusual Cause of Abdominal Pain

Abstract

Background: Brunner’s gland adenoma is a rare entity. It can cause various symptoms like bleeding, abdominal pain, and obstruction.  

Case Report: This is a case report of a 35-year-old shopkeeper who presented with a 2-month history of episodic upper abdominal pain, burning, and nausea. Upper gastrointestinal endoscopy revealed a pedunculated submucosal swelling with normal overlying mucosa at the first part of the duodenum. Endoscopic ultrasound revealed a mixed echogenic mass originating from the mucosa and submucosa. It was resected endoscopically. Histopathological evaluation of the resected polypoid mass revealed the proliferation of benign Brunner’s gland cells in the submucosal region.

Conclusion: Most of the Brunner’s gland adenomas are diagnosed by Endoscopy. Endoscopic or surgical intervention remains the mainstay of treatment.
