A primary signet ring cell cancer (SRCC) is a rare form of an adenocarcinoma of the large intestine. The prognosis of SRCC of the colon has been reported to be worse than classic adenocarcinoma of the colon; however, there is no difference in the post-operative surveillance for SRCC. We report a case of SRCC of the colon with negative resection margins that recurred at the anastomosis site 26 months after curative resection. A 55-year-old male presented to the hospital with abdominal pain. The
