Sporadic duodenal polyps are uncommon, being found at 5% of patient referred for upper endoscopy. They are often discovered incidentally and are usually asymptomatic. Endoscopic features and histologic results from endoscopically biopsied specimen cannot exclude malignancy. Recently, we experienced a Brunner's gland adenoma of duodenum mimicking malignant neoplasm. A 52-year-old female visited for evalution of a duodenal mass. A 3 cm sized polypoid mass located at the mesenteric border of 2nd portion of duodenum was found on endoscopic examination. Histologic results based on tissue taken from endoscopic biopsy showed gastric foveolar hyperplasia. Endoscopic polypectomy was performed to exclude malignancy and histological finding was consistent with Brunner's gland adenoma.
Key Words: Brunner's gland adenoma; Duodenal polyp
