[Melena associated with a Brunner's adenoma]

Area of Science:

• Gastroenterology
• Pathology
• Surgical Endoscopy

Background:

• Brunner's glands are normally found in the duodenum.
• Hyperplasia of these glands can lead to benign tumors like Brunner's adenoma.
• Gastrointestinal bleeding is a potential complication of duodenal lesions.

Observation:

• A 68-year-old female presented with collapse, anemia, fatigue, and dyspnea.
• Melena indicated upper gastrointestinal hemorrhage.
• Gastroduodenoscopy identified a duodenal polyp.

Findings:

• The duodenal polyp was successfully resected endoscopically.
• Pathological examination confirmed the polyp as a Brunner's adenoma.
• Brunner's adenoma is a benign submucosal nodular hyperplasia of Brunner's glands.

Implications:

• Endoscopic resection is an effective treatment for symptomatic Brunner's adenoma.
• Accurate pathological diagnosis is crucial for managing duodenal polyps.
• This case highlights the importance of investigating gastrointestinal bleeding causes.
