Abstract

The purpose of this study was to determine the endoscopic features of duodenal involvement in mantle cell lymphoma. Eleven patients with multiple protruding lesions were analyzed in this study. Macroscopically, multiple minute polyploid lesions, verrucous lesions, the mixed type of multiple minute polyploid lesions and verrucous lesions and submucosal tumor-like lesions were observed in 3, 3, 2 and 3 cases respectively. The multiple tiny polyploid lesions were not associated with erosive changes. Meanwhile, all verrucous lesions and submucosal tumor-like lesions presented with an erosive surface except for one verrucous lesion. In order to diagnose mantle cell lymphoma as early as possible, lesions in the duodenum presenting these endoscopic findings need to be biopsied.
