Such polyps are termed "inverted hyperplastic polyps". They appear to be restricted to the sigmoid colon and rectum. The misplaced epithelium is mucin-depleted, similar to the basal one-third of the polyp. The misplacement is accompanied by the lamina propria and is continuous with the overlying polyp through a gap in the muscularis mucosae. It ...
Biopsy of the stomach in Ménétrier disease; the substantial pit hyperplasia makes the large rugal folds appear to be covered by myriad polyps resembling hyperplastic polyps. The muscularis propria is the folded structure at the bottom center. Specialty: Gastroenterology
Fundic gland polyposis is a medical syndrome where the fundus and the body of the stomach develop many fundic gland polyps.The condition has been described both in patients with familial adenomatous polyposis (FAP) and attenuated variants (AFAP), and in patients in whom it occurs sporadically.
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.
A fundic gland polyp is a type of polyp, found in the fundus of the stomach. Fundic gland polyps are found in 0.8 to 1.9% of patients who undergo esophagogastroduodenoscopy, and are more common in middle-aged women. [2] The risk of malignancy is very low or none, when sporadic. [3]
Traditional serrated adenoma seen under microscopy with H&E stain, showing serrated crypts. SPS may occur with one of two phenotypes: distal or proximal. [6] The distal phenotype may demonstrate numerous small polyps in the distal colon and rectum, whereas the proximal phenotype may be characterized by relatively fewer, but larger polyps in the proximal colon (cecum, ascending colon, etc.). [6]
Polyps are found throughout the GI tract (most frequently in the stomach and large intestine, followed by the small intestine) though typically avoid the esophagus. [6] A biopsy will reveal them to be hamartomas; the possibility that they progress to cancer is generally considered to be low, [7] although it has been reported multiple times in the past.
Solitary juvenile polyps most commonly occur in the rectum and present with rectal bleeding. The World Health Organization criteria for diagnosis of juvenile polyposis syndrome are one of either: More than five juvenile polyps in the colon or rectum; or; Juvenile polyps throughout the gastrointestinal tract; or
