 We investigated the endoscopic and radiological findings of colorectal lymphomas from 41 cases with 45 lesions, and assessed the correlation with pathological findings. We classified morphological findings of colorectal lymphoma into three types : protruded, ulcerative, and infiltrative type. The ulcerative type lymphomas more frequently invaded to the serosa than the protruded type. Diffuse large B-cell lymphomas (DLBCL) were often of the ulcerative type, but marginal zone B-cell lymphomas from mucosa-associated lymphoid tissue (MALT) were of the protruded type and had no tendency towards invasion, compared with DLBCL. The characteristic features of colorectal lymphoma were smooth mucosal surface mimicking submucosal tumor and severe luminal narrowing without any symptom of obstruction.
