A 52-year-old woman was admitted to the hospital because of persisting back pain. She had undergone a radical modified mastectomy for right breast cancer at 49 years old and a left upper lobectomy for lung cancer at 51 years old. Abdominal computed tomography revealed each one tumor about 20mm in diameter in the pancreas head and tail. Endoscopic retrograde cholangiopancreatography revealed stenosis of the main pancreatic duct in the head and dilatation in the body and tail. The tumors were suggestive of malignancy by a cytology of pancreas juice. We diagnosed the case as multiple pancreas metastasis from breast or lung caner and performed a distal pancreatomy and a splenectomy. Histologically the excised tumors consisted of well differentiated squamous cell carcinoma and partially differentiation to adenocarcinoma. Compared with previous pathological findings of lung cancer, these pancreatic tumors were compatible with pancreas metastasis from lung cancer. After the operation her back pain disappeared, and she has remained well with other recurrence as of 1 year and 3 months. Although pancreas metastasis had poor prognosis, we should consider aggressive surgery that might prolong prognosis and improve quality of life in some cases.
