What is hyperplasia?
(HY-per-PLAY-zhuh) An increase in the number of cells in an organ or tissue. These cells appear normal under a microscope. They are not cancer, but may become cancer. Enlarge.
What is polypoid gastritis?
The term polypoid gastritis refers to a variety of nonspecific inflammatory lesions of the gastric mu- cosa which are associated with prominent gastric rugae with polypoid change.
What are hyperplastic gastric polyps?
Hyperplastic polyps appear in bunches, and are found scattered throughout the stomach. In addition, these polyps are also found near a stomach ulcer. Hyperplastic polyps are strongly linked with disorders that inflame or irritate the stomach, such as chronic gastritis, H.
What is polypoid Foveolar hyperplasia?
Polypoid foveolar hyperplasia (PFH) is regarded as a precursor of gastric hyperplastic polyps and differs slightly from them in the microscopic structure. Elongated pits of the mucosa but without features of dilatation can be also seen in PFH, and the lamina propria is either normal or only slightly swollen[2].
What are the types of hyperplasia?
There are four types of endometrial hyperplasia. The types vary by the amount of abnormal cells and the presence of cell changes. These types are: simple endometrial hyperplasia, complex endometrial hyperplasia, simple atypical endometrial hyperplasia, and complex atypical endometrial hyperplasia.
What is hyperplasia in pathophysiology?
Hyperplasia is increased cell production in a normal tissue or organ. Hyperplasia may be a sign of abnormal or precancerous changes. This is called pathologic hyperplasia.
What is a polypoid lesion in the stomach?
Any discrete lesion protruding into the lumen of gastrointestinal (GI) tract appeared at endoscopy is called as “polypoid lesion”[3]. However, a polyp is defined as a proliferative or neoplastic lesion of gastrointestinal mucosal layer[3].
What is a polypoid lesion of the colon?
Polypoid tumors of the bowel arise as fiat plaques of tissue which spread circumferentially (Fig. 1, A). The more rapidly infiltrating tumors soon invade the deeper layers of the bowel wall and encircle the bowel until the typical “napkin ring” carcinoma is produced.
Are hyperplastic polyps cancerous?
Hyperplastic polyps are typically benign (they aren’t pre-cancers or cancers) and are not a cause for concern.
What is antral gastritis?
Antral gastritis is an inflammation of the antral portion of the stomach of unknown etiology, which probably begins in the mucosa, usually involves the submucosa, and may even extend to the serosa.
