The patient was a 68-year-old man who underwent pancreaticoduodenectomy for pancreatic cancer in 2011(T3N1M0, Stage Ⅲ). Fifty-one months after surgery, 2tumors measuring about 8mm in diameter were detected in the right lung. Thus, partial resection of the right lung was performed. Histological examination of both tumors revealed a tubular adenocarcinoma, with positive staining for CA19-9 and cytokeratin 7 and negative staining for cytokeratin 20, TTF-1, and napsin A, which were diagnosed as metastasis of pancreatic cancer. Twenty-nine months after the lung operation, he died because of peritoneal dissemination. Recurrent pancreatic cancer with metastasis has a particularly poor prognosis; however, surgical resection of lung metastasis in pancreatic cancer might result in a better prognosis.
