Colorectal cancer (CRC) metastasizing to the stomach and duodenum is rare. Even rarer is when the CRC subtype is signet-ring cell carcinoma (SRCC). Endoscopic findings of CRC metastasis to the stomach have been described as solitary and submucosal while duodenal metastasis has been observed to be exophytic. In this report, we describe a case of a middle-aged man with colon SRCC presenting with oral intolerance. He was found to have concurrent metastases to the stomach and duodenum and died 8 months after his SRCC diagnosis.
