Polyps that are pedunculated (with a stalk) are usually less dangerous than sessile polyps (flat polyps). Sessile polyps have a shorter pathway for migration of invasive cells from the tumor into submucosal and more distant structures, and they are also more difficult to remove and ascertain. Sessile polyps larger than 2 cm usually contain ...
The types of polyps found in SPS include sessile serrated adenomas/polyps, traditional serrated adenomas, and hyperplastic polyps. SPS occurs in two phenotypes: proximal and distal. Proximal SPS has a greater risk of CRC than distal SPS. The vast majority of cases may be managed with colonoscopy with removal polyps (polypectomy). Polyp removal ...
The serrated polyposis syndrome (SPS) is a relatively rare condition characterized by multiple and/or large serrated polyps of the colon. Serrated polyps include SSLs, hyperplastic polyps, and traditional serrated adenomas. Diagnosis of this disease is made by the fulfillment of any of the World Health Organization's (WHO) clinical criteria. [4]
Micrograph of a sessile serrated adenoma. H&E stain. Sessile serrated adenomas are characterized by (1) basal dilation of the crypts, (2) basal crypt serration, (3) crypts that run horizontal to the basement membrane (horizontal crypts), and (4) crypt branching. The most common of these features is basal dilation of the crypts.
An endometrial polyp or uterine polyp is a mass in the inner lining of the uterus. [1] They may have a large flat base or be attached to the uterus by an elongated pedicle (pedunculated). [2] [3] Pedunculated polyps are more common than sessile ones. [4] They range in size from a few millimeters to several centimeters. [3]
For example, adenomatous polyps in the colon may be pedunculated (lobular head with a long slender stalk) or sessile (broad base). The adenomatous proliferation is characterized by different degrees of cell dysplasia ( atypia or loss of normal differentiation of epithelium) irregular cells with hyperchromatic nuclei, stratified or ...
Most polyps are benign and do not need to be removed. Surgical removal of the gallbladder (cholecystectomy) is recommended when a gallbladder polyp larger than 1 cm is found, even if the person has no symptoms clearly related to the polyp. Laparoscopic surgery is an option for small or solitary polyps. [citation needed]
A colorectal polyp is a polyp (fleshy growth) occurring on the lining of the colon or rectum. [1] Untreated colorectal polyps can develop into colorectal cancer. [2] Colorectal polyps are often classified by their behaviour (i.e. benign vs. malignant) or cause (e.g. as a consequence of inflammatory bowel disease).
