A rare case of triple colon cancers with situs inversus totalis was reported. A 52-year-old woman complaining low abdominal fullness and pain was admitted to our hospital. Chest X-P revealed dextracardia. Double contrast barium enema study revealed an apple core sign in the descending colon and a depressive lesion in the transverse colon in addition to situs inversus. Colonoscopic finding revealed an advanced cancer in the descending colon, but fiberscope could not be further inserted because of narrowing due to the tumor. A moderately defferentiated adenocarcinoma was confirmed by biopsy. CT revealed a liver tumor in the right lobe in addition to situs inversus. Hemicolectomy and liver wedge resection were performed. Histology of the resected colon demonstrated an advanced colon and an early cancer in the desoending colon and an early colon cancer in the transverse colon. The resected liver demonstrated a metastatic tumor from colon cancer.
