We report a case of synchronous quadruple cancers including hepatocellular carcinoma (HCC) and liver metastasis from colon cancer (CLM). A 76-year-old man was diagnosed as having a left lung tumor and three hepatic tumors in segment 7 (S7), S3 and S4 by CT at 7 months after operation for the descending colon cancer in another hospital. Furthermore, since carcinoma in situ of the ascending colon was found by colonoscopy, endoscopic mucosal resection was performed. Left upper lobectomy for lung tumor was performed, and this tumor was pathologically diagnosed as primary lung adenocarcinoma. Afterward, he was introduced to our department for treatment of the liver tumors. The S7 tumor was diagnosed as HCC, and S3 and S4 tumor as CLM in imaging examinations. Partial resections for each three tumor were performed and final pathological diagnosis was in accord with a preoperative diagnosis. Since synchronous quadruple cancers including HCC and CLM were extremely rare, we report this case with reviews of the literature.
