Molecular characteristics of colorectal serrated polyps and hyperplastic polyps
The serrated neoplasia pathway of colorectal carcinogenesis is characterized by BRAF mutation and aberrant DNA methylation, which have not been reported on Korean patients. The aim of this study was to investigate BRAF mutation and DNA methylation in colorectal serrated polyps and the right colon.Between 2005 and 2013, 146 colon polyps (47 tubular adenomas [TAs], 53 traditional serrated adenoma...
متن کاملThe clinical impact of serrated colorectal polyps
Serrated polyps (SPs) of the colorectum pose a novel challenge to practicing gastroenterologists. Previously thought benign and unimportant, there is now compelling evidence that SPs are responsible for a significant percentage of incident colorectal cancer worldwide. In contrast to conventional adenomas, which tend to be slow growing and polypoid, SPs have unique features that undermine curren...
متن کاملSessile serrated lesion misdiagnosed as a hyperplastic polyp.
An 81-year-old woman presented for colonoscopy because of iron deficiency anemia. She had undergone colonoscopy 5 years previously during which a 2-cm prominent fold had been identified in the proximal ascending colon (●" Fig.1). A biopsy of this lesion was interpreted as being a hyperplastic polyp (●" Fig.2), although the polyp showed features of a serrated lesion. Because of clinical concern ...

15 صفحه اولHyperplastic polyps and serrated adenomas: precancerous lesions with mixed immunophenotype.
Our immunohistochemical study wants to be a contribution to clarifying the adenoma-carcinoma sequence and serrated pathway of colorectal carcinogenesis. Thus, we performed immunohistochemical analysis of hyperplastic polyps (HP), serrated adenomas (SA), and classical adenomas (tubular adenomas - TA and tubulovillous adenomas - TVA) and carcinomas developed from adenomas (CA) using expression of...
