The primary diffused infiltrating type of colonic cancer is characteristically rare, and has a high rate of malignancy. A 54-year-old Japanese man was admitted to our hospital complaining of abdominal pain and decreased stools. Sigmoid colonic cancer was suspected as a result of the Ba-enema and colonic fiberscopy examination, but the biopsy results were negative. The sigmoid colon was resected extensively. Histopathologically, the cancer was diagnosed as being a signet ring-cell carcinoma of the sigmoid colon. Although the patient received postoperative chemotherapy, he died of carcinomata peritonitis 175 days after surgery.
