Antral type mucosa is the thin layer of tissue that lines the antrum, cardia, and pylorus of the stomach. The tissue is made up of different types of cells that produce and secrete various substances, including mucus and hormones which aid in digestion.
Antral type mucosa with chronic gastritis means inflammation in the antrum, cardia, or pylorus of the stomach. The most common cause of chronic gastritis is infection with the bacteria Helicobacter pylori. Less common causes include nonsteroidal anti-inflammatory drugs (NSAIDs), bile reflux, excessive alcohol consumption, and autoimmune gastritis.
Antral type mucosa with intestinal metaplasia means that the normal antral cells have been replaced by cells normally found in a part of the digestive system called the small intestine. These intestinal cells include specialized goblet cells that look blue when examined under the microscope because they contain a large amount of mucin. Intestinal metaplasia in the stomach is commonly caused by long-standing inflammation.
Antral mucosa with reactive changes means that the tissue has been injured and looks abnormal when examined under the microscope. The injury can be caused by infection, physical stress, or exposure to chemicals or medications. Reactive does not mean cancer.
