A Case of Resected Multiuple Pulmonary Metastases From Gastric and Colon Cancer

Abstract

Background. In the case of resected multiple pulmonary metastases from gastric and colon cancer, it was difficult to differentiate the pulmonary metastases from primary cancer. Case. A 62-year-old woman underwent subtotal gastrectomy and hemicolectomy because of gastric and the colon cancer. Eighteen months later, she was found to have a pulmonary nodule in the left upper lobe on a chest computed tomography (CT). She underwent left upper lobectomy because the tumor was not diagnosed by the frozen microscopic findings. The tumor was diagnosed as a lung metastasis from colon cancer pathologically. She was found to have an another pulmonary nodule in the right upper lobe on the follow up CT scan. She underwent right upper lobectomy and the tumor was diagnosed as lung metastases from gastric cancer. Conclusion. We report a case of multiple metastases from gastric cancer and colon cancer.
