Background. Reports of multiple ground-glass nodules (GGNs) have been increasing due to the recent spread of high resolution CT (HRCT). We herein report a case of synchronous double cancers: colon and multiple primary lung coexisting with sclerosing pneumocytoma. Case. A 69-year-old woman was diagnosed colon cancer in July 2015 and transverse colectomy D3 dissection was performed. The pathological diagnosis was tubular adenocarcinoma (tub1), pT3(ss)N0M0 stage IIA. She was introduced to our division, because chest HRCT showed bilateral multiple GGNs, a part-solid GGN and a solid nodule. We therefore suspected multiple primary lung cancers and a metastatic lung tumor. At first, we performed right upper lobectomy and wedge resection of the right lower lobe in September 2015. The pathological diagnosis was as follows, four pure GGNs of right upper lobe were all non-invasive adenocarcinomas and a solid nodule of the right lower lobe was sclerosing pneumocytoma. We then performed left superior segmentectomy in November 2015. The pathological diagnosis was minimally invasive adenocarcinoma. She underwent bilateral lung resection; however, her post-operative condition was very good and she comes to our hospital regularly. Conclusion. We reported a case of synchronous double cancer: transverse colon and multiple primary lung cancer coexisting with sclerosing pneumocytoma. We could resect the colon tumor and all of the lung tumors.
