A sessile polyp is a growth that is relatively flattened, in contrast with a pedunculated polyp, a growth that develops on a protruding stalk. These growths are usually benign in nature, although they can become malignant. When a polyp is identified, it is possible to conduct some diagnostic...
It seems like the sessile polyp is not a type of malignant polyp, at least not usually. That's a good thing, since it is not easy to locate on the body. However, I would still be worried about any sort of polyp if I had one, and probably want it removed even if it was benign...
What causes pedunculated polyp? Research suggests that sessile serrated polyps result from acombination of a mutation in a gene called BRAF and a process called promoter hypermethylation, which makes cells more likely to become cancerous. Put simply, the mutated gene causes cells to divide, which ...

Serrated polyps of the colorectum are now understood to be a heterogeneous group of polyps, some of which are cancer precursors, such as the sessile serrated adenoma (SSA) and the traditional serrated adenoma (TSA). In contrast to conventional adenomas, there is limited published literature on ...
(0.05%), while group 2 comprised cases with hyperplastic polyp (0.53%), sessile serrated adenoma (0.83%), low-grade mucinous neoplasia (0.28%), neuroendocrine cell proliferation (0.28%), neuroendocrine tumor (NET) (1.2%), gastrointestinal stromal tumor (0.02%), and ...
Sessile polyp in the ascending colon, submerged entirely under tagged residual fluid.aAxial 2D view shows a sessile polyp (arrow) with a homogeneous soft tissue attenuation within the tagged hyper-dense fluid.bIn the corresponding endoluminal view, only a horizontal fluid layer is seen (arrowheads)...
After excluding patients who had previously been designated as having "borderline or indeterminate" serrated polyp, the prevalence of SSA/P with LGD, HGD, and CRC in our cohort (7.7%, 0.59%, and 0.03%, respectively) was still lower than the reported rates in the prior study from this insti...
Figure 01: Hyperplastic Polyp There are several types of hyperplastic polyps that vary according to their shape: pedunculated (long and narrow with a mushroom-like stalk), sessile (shorter and squat looking), and serrated (flat, short, and wide around the bottom). Developing multiple hyperplastic...
