説明

We report a case of rectal metastasis from gastric cancer. The patient was a 69-year-old man with diarrhea as his major symptoms, who underwent a distal gastrostomy for gastric cancer 2 years previously. We suspected primary or metastatic rectal cancer from colonoscopic examination and barium enema. A lower anterior resection was performed. Postoperative historical examination identified poorly differentiated adenocarcinoma and signet cell carcinoma identical to the gastric cancer. Finally the lesion was diagnosed as metastatic rectal cancer from gastric cancer that showed same pattern in PAS stain. There were only 40 cases in reports in the literature from 2002 to 2012, to our knowledge. We report a rare case.
