Abstract
A 79-year-old female underwent surgery for right breast and pancreatic cancer. Eight months after the operation for pancreatic cancer, a tumor, suspected as primary lung cancer, was pointed out in the left lower lobe (S10) on CT. We decided on surgery because of no distant metastasis detected on PET and MRI. We performed VATS partial resection of the left lower lobe due to a metastatic tumor from pancreatic cancer based on the cytodiagnosis via intra-operative aspiration biopsy. Cases of resectable solitary lung metastasis from pancreatic cancer are very rare. The differentiation of this tumor as a metastatic tumor from pancreatic or primary lung cancer is difficult. However, we consider that cytodiagnosis via intraoperative aspiration biopsy is useful.
