Eight sessile serrated adenoma (SSA), right colon polypectomies with focal invasive adenocarcinoma or high-grade dysplasia were studied to identify...
This observation is supported by a study showing that occurrence of adenomas with advanced dysplasia in the distal colon is predictive of advanced lesions in total colonoscopy [30]. In addition, we found that HGD in any synchronous polyp was also associated with an increased overall number of ...

To the best of our insight, this is the first manifestation ever reported in the literature regarding the coexistence of solitary Peutz-Jeghers-type polyp, colitis cystica profunda, and high-grade dysplasia of the epithelium of the colon. The purpose of this case report is to highlight colitis...
A 20mm erythematous pedunculated polyp was observed in the sigmoid colon. Magnified endoscopy revealed a tubular or branch-like pit pattern with localized areas of irregular pits. These findings were suggestive of colorectal adenoma with high-grade dysplasia, and endoscopic mucosal resection was ...
