Gastroenterological Endoscopy 55 ( 8 ) "2167 - 74" 2013.8

Language：Japanese Publisher：Japan Gastroenterological Endoscopy Society

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.

World journal of gastrointestinal endoscopy 5 ( 1 ) 34 - 8 2013.1

Language：English Publishing type：Research paper (scientific journal) Publisher：Baishideng Publishing Group Inc.

A 69-year-old Japanese female was diagnosed with primary intestinal follicular lymphoma. Esophagogastroduodenoscopy with high-definition imaging revealed not only the typical feature of whitish polyps of up to 2 mm in diameter in the duodenal second and third portions, but also more detailed morphology, such as enlarged whitish villi and tiny whitish depositions. These findings appeared to reflect the pathological structures; infiltration of lymphoma cells into the villi were probably seen as enlargement of the villi, and the formation of lymphoid follicles were shown as opaque white spots or tiny white depositions. Thus, the above features might contribute to the distinct diagnosis of intestinal follicular lymphoma. This case indicates that routine esophagogastroduodenoscopy can visualize microsurface structures, which can be pathognomonic and help to diagnose intestinal follicular lymphoma, even without magnifying endoscopy.
