- Follicular lymphomas, which typically arise in the lymph nodes with spleen, liver, and bone marrow involvement, have generally low occurrence rates in Asian countries as compared with Western countries. Follicular lymphomas of the gastrointestinal tract are rare, and primary colonic follicular lymphomas are particularly rare compared with others found in the small intestine and duodenum. Colonoscopic imaging of colonic lymphomas, including follicular lymphoma, may reveal mucosal ulcerations, erosions, indurations, polypoid mass-like lesions, and diffuse mucosal nodularity. Herein, we report a unique case of a follicular lymphoma of the transverse colon characterized by four sessile diminutive polyps located intermittently with multiple lymph node involvement in a 62-year-old man.

Optical diagnosis of polyp histology can potentially result in enormous cost savings by way of the "resect and discard" strategy for diminutive polyps and the "do not resect" strategy for diminutive hyperplastic polyps in the distal colon. Narrow Band Imaging (NBI) highlights the surface mucosal and vascular pattern on polyps and has been shown to accurately characterize adenomatous and hyperplastic polyps by experts. However, the results have been a little discouraging amongst lesser experienced endoscopists. Studies have also shown that using the NBI diagnosis of diminutive polyp histology, experts can accurately define the future surveillance colonoscopy intervals. However nonexperts in academic or community setting have as yet failed to achieve the recommended thresholds. The subjectivity in assessment by endoscopists leads to the variable accuracy rates and can be circumvented by computer based automated tools. Although initial experience with a few computer based algorithms have shown accuracies comparable to experts, further refinement and validation will be required before these can be implemented in clinical practice. Incorporation of optical diagnosis of diminutive polyps into clinical practice is bound to face several hurdles. But the potential for enormous cost saving makes it an attractive strategy that can make colonoscopy more cost effective.

- A series of 241 polyps from 127 patients endoscopically removed during the period from march 1991 through July 1992 at our department were analysed. The following items were studied. 1) Incidence, age, and sex distrlbution of the patients 2) Number of the calonic polyps 3) Histologic classification and polyp size 4) Anatomic distribution and polyp size 5) Gross types and polyp size 6) Hietopathologic types and polyp size In conclusion, colonic diminutive polyps should not be ignored or overlooked clinically. The majority were neoplastic polyps. It is suggested that diminutive polyps should be removed endoscopically if possible
