Abstract
We reported a rare case of metachronous metastatic stomach cancer arising from descending colon cancer. A 57-year-old woman underwent an operation for descending colon cancer in January 2014. She was diagnosed with moderately differentiated p-stage II adenocarcinoma of the descending colon by pathology. Five months later, CEA level in the blood increased to 16.9 ng/mL. Dynamic CT revealed a large submucosal tumor in the upper area of the stomach. We strongly suspected recurrence of the descending colon cancer and performed total gastrectomy of the submucosal tumor in the upper area of the stomach. During surgery, we also found a submucosal tumor in the small intestine, which was partially resected. Pathology confirmed that those tumors derived from the descending colon cancer. Six months post-gastrectomy, the patient is alive with no signs of recurrence.
