2. Polyp (medicine) - Wikipedia

   en.wikipedia.org/wiki/Polyp_(medicine)

   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.

3. Serrated polyposis syndrome - Wikipedia

   en.wikipedia.org/wiki/Serrated_polyposis_syndrome

   Sessile serrated adenoma seen under microscopy with H&E stain. Serrated polyposis syndrome often does not cause symptoms. The risk of colon cancer is between 25 and 40%. [8] Sessile serrated polyps, as seen during endoscopy or colonoscopy, are flat (rather than raised) and are easily overlooked.

4. Sessile serrated lesion - Wikipedia

   en.wikipedia.org/wiki/Sessile_serrated_lesion

   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]

5. Colorectal polyp - Wikipedia

   en.wikipedia.org/wiki/Colorectal_polyp

   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).

6. Fundic gland polyposis - Wikipedia

   en.wikipedia.org/wiki/Fundic_gland_polyposis

   These symptoms include: epigastric pain; nausea; vomiting; weight loss; The polyps on endoscopy are usually tiny, numerous and sessile, [3] and usually scattered throughout the fundus of the stomach, where parietal cells are more numerous. They have the same colour as the gastric mucosa, and never have a stalk. [4]

7. Traditional serrated adenoma - Wikipedia

   en.wikipedia.org/wiki/Traditional_serrated_adenoma

   Traditional serrated adenoma is a premalignant type of polyp found in the colon, often in the distal colon (sigmoid, rectum). Traditional serrated adenomas are a type of serrated polyp, and may occur sporadically or as a part of serrated polyposis syndrome. Traditional serrated adenomas are relatively rare, accounting for less than 1% of all ...

8. Gallbladder polyp - Wikipedia

   en.wikipedia.org/wiki/Gallbladder_polyp

   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]

9. Nasal polyp - Wikipedia

   en.wikipedia.org/wiki/Nasal_polyp

   This extracellular fluid collection causes polyp formation and protrusion into the nasal cavity or sinuses. Polyps which are sessile in the beginning become pedunculated due to gravity. [11] In people with nasal polyps due to aspirin or NSAID sensitivity, the underlying mechanism is due to disorders in the metabolism of arachidonic acid.
