title: A case of multiple mucosa-associated lymphoid tissue (MALT) lymphoma of the colon identified as simple mucosal discoloration.
abstract: Most colonic multiple mucosa-associated lymphoid tissue (MALT) lymphomas are confirmed with a histologic and immunohistochemical staining of the mucosal biopsy specimen obtained during colonoscopic examinations. Endoscopically, colonic MALT lymphomas frequently appear as protruding and/or ulcerative lesions, and there are not so many reports of colonic MALT lymphoma as compared to the frequent reports of MALT lymphoma of stomach. We report a unique case of colonic MALT lymphoma presenting as a simple reddish discoloration of mucosa; this presentation has never been describe before. Our patient was a 47-yr-old male who suffered from tenesmus and mucoid stool. A colonoscopy was accomplished, followed by a histologic examination and we diagnosed a colonic MALT lymphoma. Staging of the disease was done because this was necessary for choosing the modality of treatments. The patient was then treated with polychemotherapy in conjunction with radiation therapy.
