A 61???yo male presented with esophageal polyps, which on biopsy showed gastric cardia/foveolar mucosa with intestinal metaplasia and foci of low-grade dysplasia. Extensive hot snare polypectomies were performed followed by RFA. At repeat EGD, four months later, an esophageal mass was found. ...
Introduction Non-polypoid low-grade dysplasia in inflammatory bowel disease is associated with a medium increased risk of colorectal cancer, while treatment recommendations remain controversial. We aim to evaluate the efficacy and safety of endoscopic treatment for non-polypoid dysplasia in patients with ...
Low-grade dysplasia should garner similar respect to high-grade dysplasia, if for no other reason than the difficulty that expert pathologists have with distinguishing low-grade dysplasia from high-grade dysplasia. There is no sure way to reduce the likelihood that dysplasia will arise in UC. ...

Adenomatous changes were observed within two hyperplastic polyps and low grade dysplasia in one adenoma. Histopathologic evaluation of the surrounding gastric mucosa demonstrated chronic gastritis in 72 (79%) patients and H pylori infection in 45 (49%).CONCLUSION: Hyperplastic polyps are the most ...

According to WHO's criteria these tumours consisted of 61 adenomas with low grade dysplasia (LGD), 30 adenomas with high grade dysplasia (HGD) and 19 carcinomas with submucosal invasion. Apoptotic cells were detected by TUNEL staining. Proliferating cells and apoptosis-related gene products were ...
In this study KRAS mutation occurred with the same frequency in adenomas with low-grade (48%) and high-grade (50%) dysplasia. KRAS mutation is very strongly associated with a villous architecture and through villous component expansion, KRAS mutations may increase risk of tumor progression in ...
(H.pylori)eradication.A 58-year-old male patient was referred to the outpatient clinic for evaluation and treatment of gastric low-grade dysplasia(LGD).ESD was performed.A PNS was developed at the ESD site.An endoscopic biopsy was done and there was no histological evidence of remnant tumor ...
