A case of metastatic colon cancer from gastric cancer which was difficult to differentiate from crohn's disease because of the unique radiograph

Abstract

A 60-year-old man consulted our hospital because of upper abdominal pain, anorexia, weight reduction, and diarrhea ; gastrointestinal fibroscopy revealed type 4 advanced gastric cancer with signet-ring cell carcinoma. Abdominal computed tomography (CT) revealed diffuse wall thicknening from the ascending colon to the descending colon. Extended narrowing of the bowel canal and cobblestone appearance were revealed by barium enema radiography and colonoscopy. Under the diagnosis of gastric cancer with Crohn's disease, total gastrectomy and subtotal colectomy from the ileum end to the descending colon were performed.
Histological findings revealed poorly differentiated adenocarcinoma with signet-ring cell carcinoma in the specimens of both the stomach and the colon.
We reported a rare case of metastatic colon cancer from gastric cancer which was difficult to differentiate from Crohn's disease because the unique radiograph.
