There are three main theories as to how metaplasia occurs:
Intestinal Metaplasia is the replacement of normal gastirc cells to another diffentiated cell type. The most common cause of this type if metaplasia is the result of chronic gastritis. During chronic gastritis you have atrophy of the mucosa which leads to decrease in acid secretion and mucous secretion, which quickly conducts ulcers. The constant regenerative response to such ulcers leads to metaplsia and eventually lead to foveolar hyperplasia, and then dysplasia
Metaplasia is when the cells in a certain area of the body change from one cell type to another. For example in the stomach the epithlium (cells that make up the lining of the stomach) is normally a columnar type of cell. However, certain stimuli can change the type of cell leading to an abnormality.
In the stomach it would most likely be a sign of cancer, however, metaplasia of the stomach is very rare. Metaplasia of the esophagus or the intestine is much more common and is caused by conditions of the stomach being abnormal such as gastric reflux causing metaplasia in the esophagus and too much acid secretion from the stomach causing metaplasia in the intestine.
No. Metaplasia is not a cancer. In metaplasia one type of epithelium is changed to another type of epithelium.
Metaplasia is the result of acid reflux and it can flare up again to cause grade 1 oesophagitis which is usually due to acid reflux from the stomach
What age does agnogenic myeloid metaplasia usually happen at?
I suspect you mean antral metaplasia, when some of the cells of the stomach lining change structure and look more like intestinal lining cells.
hii
no
Murray N. Silverstein has written: 'Agnogenic myeloid metaplasia' -- subject(s): Myeloid metaplasia
Metaplasia (refferig to a cell)
Yes
diagnosis ulcerated gastric hyperplastic poly with focal intestinal metaplasia with lymphoplasmactic infiltrate also gastric oxyntic-type mucosa with lymphoid aggregate what does this mean
No it's reversible once injurious stimulus is removed.
yes it can
