Endoscopic Mucosal Resection of a Large Brunner's Gland Adenoma: A Case Report

Abstract

Background: Brunner's gland adenoma is a rare, benign small-bowel tumor. Although asymptomatic, it has been reported to cause complications like gastrointestinal bleeding. We present the case of a 28 year-old Filipino male who presented with recurrent melena from a duodenal polypoid mass, successfully removed by endoscopic mucosal resection. Histopathologic examination of the mass revealed findings consistent with Brunner's gland adenoma. The patient recovered uneventfully. No recurrence of gastrointestinal bleeding was noted thereafter.

Conclusion: Brunner's gland adenoma is a rare benign duodenal lesion. We presented a case of rare Brunner's gland adenoma presenting as gastrointestinal bleeding. We successfully removed the lesion by endoscopic mucosal resection. Endoscopic mucosal resection is a safe and low-risk treatment for large and symptomatic Brunner's gland adenoma.
