ABSTRACT
Villous adenomas of the ampulla of Vater are rare premalignant tumors that have been reported to occur in 0.04% to 0.12% of postmortem series. Traditionally surgical treatment has been used but it might result in significant morbidity and mortality. This case is a villous adenoma of ampulla of Vater found incidentally, but successfully removed by endoscopic method. After endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasonography (EUS), we resected the tumor of ampulla of Vater endoscopically using endoscopic mucosal resection (EMR) method. The post-procedure course was uneventful. Here we report an ampullary adenoma resected by endoscopic method in a 42-year-old man with villous adenoma of the ampulla of Vater.

An anomalous pancreaticobiliary ductal union is a rare anomaly occurring in the biliary tract. This anomaly has been implicated as a cause of choledochal cysts, bile duct and gallbladder carcinoma, and recurrent pancreatitis. A case is herein reported of a 63 year-old woman who suffered from gallbladder cancer associated with a choledochal cyst and an anomalous pancreaticobiliary union.

Lung cancer metastatic to the small intestine is uncommon. Despite the widespread nature of metastases that characterize this carcinoma, symptomatic intestinal metastases are extremely rare, but have been reported as a cause of intestinal obstruction, hemorrhage, malabsorption, and perforation. We have recently encountered two cases with squamous cell lung cancer who underwent endoscopic retrograde cholangiopancreatography for obstructive jaundice. Biopsies obtained from concentric ulcerative mass in the duodenum showed metastatic squamous cell carcinoma in the lymphatics. Histologically, the pulmonary and duodenal lesions were identical and this suggests a lymphatic route of dissemination. This is the report of two cases with obstructive jaundice secondary to duodenal metastasis from primary lung cancer. Metastatic squamous cell carcinoma of the lung to the duodenum should be considered in the differential diagnosis of patients harboring such a malignancy who have obstructive jaundice.
