Resection of synchronous lung and Vater's papilla cancer.

We present a case of a 78-year-old man with a synchronous double cancer of the lung and Vater's papilla. A pancreaticoduodenectomy was performed for Vater's papilla cancer and a partial lung resection for lung cancer. Thepathological diagnosis of the tumors was a well differentiated tubular adenocarcinoma and well differentiated bronchioloalveolar carcinoma, respectively. Although most cases of synchronous double cancers involve lung and gastric cancers, a combination of lung and Vater's papilla is extremely rare. This patient is still alive with no recurrence for 5 years after the last operation.
