Ampullary tumors manifest as symptoms of biliary (jaundice) and/or pancreatic (pancreatitis) obstruction, but incidental diagnoses are frequent.[1] Endoscopically, there could present as a proliferative extra-ampullary tumor or more rarely as an intra-ampullary tumor (16% of patients).[1] The intra-ampullary submucosal tumors are mainly adenoma/adenocarcinoma and neuroendocrine tumor.[1] Rare cases of adenomyoma, intra-ampullary papillary–tubular neoplasm, gastrointestinal stromal tumor, lipoma, lymphangioma, and gangliocytic paraganglioma have been reported.[2] Endoscopic resection is the first-line treatment when feasible. Depending on the histological analysis, additional surgical treatment may be necessary.[1] Here, we report the first case described of an intra-ampullary Brunner's gland adenoma.

A 50-year-old woman presented with diffuse abdominal pain, finally related to sexually transmitted infection. She had a history of human immunodeficiency viruses and alcoholism. Blood test revealed a moderate cholestatic jaundice and important cytolysis (bilirubin: 1.4 mg/dL, alkaline phosphatase (PAL): 985 UI/L, gamma-glutamyl transferase: 3825 UI/L, alanine aminotransferase: 315 UI/L, and aspartate aminotransferase: 421 UI/L). A computed tomography scan and a magnetic resonance imaging showed double-duct dilation (common bile duct diameter at 14.5 mm and main pancreatic duct at 6.5 mm) and obstruction at the papilla without duodenal mass [Figure 1]. No lymph node invasion or metastasis was suspected. Endoscopic ultrasound confirmed a rounded little isoechoic homogeneous intra-ampullary tumor, responsible for double-duct dilation [Figure 1]. A papillectomy was performed without any further complication, and a protective pancreatic stent was easily positioned.

The histopathologic examination showed ampulla mucosa covered by flattened villi. In the submucosa, we observed a nodular proliferation of normal Brunner's glands. The lesion corresponded to an intra-ampullary Brunner's gland adenoma [Figure 2].

Brunner's glands are located mainly in the deep mucosa and submucosa of the duodenum (D1–D2). These glands secrete mucus which plays a role in neutralizing acidic gastric juice. Brunner's gland adenoma is a rare cause (less than 5% of benign duodenal tumors) of duodenal polyp with reported cases of bleeding and duodenal obstruction.[3] The pathogenesis of Brunner's gland adenoma remains poorly understood.[3] The risk of cancer remains debated, but cases of high-grade dysplasia and invasive cancer have been described.[3]
