What is a elongated polyp?
Colonic mucosubmucosal elongated polyp (CMSEP) is a distinctive non-neoplastic colorectal polyp characterized by pedunculated, elongated shape and is composed mainly of expanded submucosa with a normal mucosal lining. Only a small number of these polyps have been reported, exclusively from Japan.
What is a submucosal polyp?
Most of the colonic submucosal mesenchymal polyps are benign tumors. They are formed by more than one type of mesenchymal tissue. The diagnosis of angiolipofibroma depends on the histological findings with the proliferation of vascular, fatty, and fibrous connective tissues.
Is colonic mucosa a polyp?
The colonic mucosa is studded with innumerable sessile and small pedunculated polyps, which involve the entire length of the specimen. Colonic resection is also advocated for patients with long-standing ulcerative colitis who have developed high-grade dysplasia or a dysplasia-associated lesion or mass (DALM).
Are colonic polyps serious?
Most colon polyps are harmless. But over time, some colon polyps can develop into colon cancer, which may be fatal when found in its later stages. Anyone can develop colon polyps.
What percentage of stomach polyps are cancerous?
Although most stomach polyp types are harmless, some stomach polyps occur due to the presence of cancerous cells. These account for about 1–2% of the stomach polyps that doctors find during endoscopies.
Can polyps in uterus come back?
Uterine polyps, once removed, can recur. It’s possible that you might need to undergo treatment more than once if you experience recurring uterine polyps. If the polyps are found to contain precancerous or cancerous cells, hysterectomy (removal of the uterus) may become necessary.
Should gastric polyps be removed?
Because of the increased risk of cancer, all adenomatous polyps should be removed. Removal is usually done with an endoscope. The doctor may recommend surgery if there are many of these polyps and if the cancer has begun to spread.
What is colonic mucosa?
Colonic mucosa is a term used to describe the specialized tissue that covers the inside of the colon. The colon is a long, hollow organ and part of the digestive tract. It starts at the end of the small bowel (the ileum) and ends at the anal canal.
Should I worry about stomach polyps?
Most stomach polyps don’t become cancerous. But certain types can increase your risk of stomach cancer. Depending on the type of stomach polyp you have, treatment might involve removing the polyp or monitoring it for changes.
What are the endoscopic features of muco-submucosal elongated polyps?
Irrespective of site, muco-submucosal elongated polyps display characteristic endoscopic features, with a “worm-like” appearance which are lined by unremarkable mucosa.
What are benign gastrointestinal polyps composed of mucosa and submucosa?
Benign gastrointestinal polyps composed of mucosa and submucosa, the latter with a prominent vascular component are relatively unusual non-neoplastic lesions with uncertain etiopathogenesis. Such polyps have mainly been studied by Japanese investigators, but are increasingly being recognized by western investigators[1,2].
What is cmsep polyp?
Colonic mucosubmucosal elongated polyp (CMSEP) is a distinctive non-neoplastic colorectal polyp characterized by pedunculated, elongated shape and is composed mainly of expanded submucosa with a normal mucosal lining. Only a small number of these polyps have been reported, exclusively from Japan.
What is the typical size of a colonic polyp?
Polyp size ranged from 10 to 150 mm. Histologically, CMSEPs were characterized by unremarkable large bowel mucosa and submucosal stalk containing dilated thick-walled veins running parallel to the long axis of the polyp. Mucosal inflammation or fibromuscular proliferation characteristic of mucosal prolapse was absent.
