aAll types of endometrial hyperplasia (cystic, adenomatous, atypical) can cause diffusely smooth or, less commonly, focal hyperechoic endometrial thickening (Fig 23). The US appearance can simulate that of normal thickening during the secretory phase, sessile polyps, submucosal fibroids, cancer, ...
with tentacles lining the inner edge of the bowl. The mouth is also located on the underside of the medusa. Thepolypoidform, by contrast, is a sessile (immobile) cnidarian that attaches to the sea floor or other solid aquatic features. Polyps are characterized by a tube-shaped body that is...
Flat polypsare the least common type of colon polypand are flat or even slightly depressed. These may be difficult to identify because they are not as prominent as polypoid or sessile polyps with the commonly available methods of diagnosing polyps. What are the types of colon polyps? Not all ...
Accurate endoscopic criteria are needed to differentiate serrated polyps, including hyperplastic polyp (HP), sessile serrated adenoma/polyp (SSA/P), and traditional serrated adenoma (TSA), because some are precursors of colorectal cancers. To determine the endocytoscopic features of each type of ...
Sessile polypsdo not have a stalk and are attached to the lining by a broad base. Flat polypsare the least common type of colon polypand are flat or even slightly depressed. These may be difficult to identify because they are not as prominent as polypoid or sessile polyps with the commonly...
Polypoid-type carcinomas were pedunculated, subpedunculated, or sessile polyps. Superficial-type carcinomas were flat lesions with a smooth, even surface. Granular-type, laterally spreading tumors were superficially spreading lesions with aggregates of nodules and a granular surface. Apoptotic cells were...
In hyperplastic polyps and the majority of sessile serrated, and traditionally serrated adenomas the expression of PTEN was decreased. In tubular and tubulo-villous adenomas the expression of this marker changes mostly in case of high grade intraepithelial neoplasia. Our results confirm early changes ...
Of those 139 (M 64/F 75), mean age 59.9, (range 50-80) were found to have sessile polyps measuring up to 6 mm and were randomized to undergo polypectomy with the RJ4 (n=70) or the RJ3 (n=69) forceps. In these patients a total of 302 eligible polyps were detected (151 ...
Figure 1.Toll-like receptor (TLR) mRNA expression levels based on relative expression (RQ) in different types of histological polyps: Distribution of TLR2, TLR3, TLR4, and TLR5 mRNA expression levels between normal, hyperplastic (HP), sessile serrated adenoma (SSA), villous/tubulovillous (VP...
