We present a 71-year-old man with mucosa-associated lymphoid tissue (MALT) lymphoma of the colon presenting with massive gastrointestinal hemorrhage. At laparotomy two areas of irregular mucosa were noted in the ascending colon and cecum. Pathology revealed MALT lymphoma. MALT lymphoma of the colon is rare and the presentation as well as outcome of our case makes him unique.
