title: A case of a pancreatic tumor that was diagnosed as metastasis from lung cancer by endoscopic ultrasound-guided fine needle aspiration.
abstract: Metastatic tumors are rare in the pancreas, and some cases are difficult to distinguish from pancreatic cancer. However, distinguishing between them is very important to formulate a treatment plan. A case of a rare disease, called overlap cancer, involving metastatic tumors to the pancreas and right kidney from lung cancer, and duodenal papilla cancer, is described. Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is useful for diagnosing metastatic pancreatic tumors, particularly in patients with multiple cancers.
