A polyp is an abnormal growth of tissue projecting from a mucous membrane. If it is attached to the surface by a narrow elongated stalk, it is said to be pedunculated; if it is attached without a stalk, it is said to be sessile. Polyps are commonly found in the colon, stomach, nose, ear, sinus(es), urinary bladder, and uterus.
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]
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]
A cervical polyp is a common benign polyp or tumour on the surface of the cervical canal. [2] They can cause irregular menstrual bleeding but often show no symptoms. Treatment consists of simple removal of the polyp and prognosis is generally good. About 1% of cervical polyps will show neoplastic change which may lead to cancer.
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 ...
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.
The same goes for vitamin B12 and ferritin (a form of iron) which women may not get enough of via food, particularly those following plant-based or vegetarian diets.
It may appear white or normal colored. It may be pedunculated or sessile. The average size is between 1–5 cm. Neither sex is significantly more likely to develop them. The most common site is the palate-uvula area followed by tongue and lips. Durations range from weeks to 10 years.
