title: A case of ascending colonic xanthoma presenting as a lateral spreading tumor.
abstract: Gastrointestinal xanthomas are characterized by foamy cytoplasmic cells containing lipid in lamina propria, and occur almost in the gastric mucosa. Colonic xanthomas have been described in rare case. All reported colonic xanthomas were located in rectosigmoid. Rectosigmoid xanthomas have tended to exhibit small polypoid lesion, on the contrary flat in stomach. We report a case of xanthoma on ascending colon presenting as a laterally spreading tumor resected by endoscopic mucosal resection method.
