Micrograph showing apocrine metaplasia of the breast with typical features [3] H&E stain. Barrett's esophagus is an abnormal change in the cells of the lower esophagus, thought to be caused by damage from chronic stomach acid exposure. The following table lists some common tissues susceptible to metaplasia, and the stimuli that can cause the ...
Barrett's esophagus is marked by the presence of columnar epithelia in the lower esophagus, replacing the normal squamous cell epithelium—an example of metaplasia. The secretory columnar epithelium may be more able to withstand the erosive action of the gastric secretions; however, this metaplasia confers an increased risk of adenocarcinoma.
Intestinal metaplasia is the transformation of epithelium (usually of the stomach or the esophagus) into a type of epithelium resembling that found in the intestine. In the esophagus, this is called Barrett's esophagus .
The most common example of metaplasia is Barrett's esophagus, when the non-keratinizing squamous epithelium of the esophagus undergoes metaplasia to become mucinous columnar cells, ultimately protecting the esophagus from acid reflux originating in the stomach. If stress persists, metaplasia can progress to dysplasia and eventually carcinoma ...
Esophageal strictures – the persistent narrowing of the esophagus caused by reflux-induced inflammation; Barrett's esophagus – intestinal metaplasia (changes of the epithelial cells from squamous to intestinal columnar epithelium) of the distal esophagus [20] Esophageal adenocarcinoma – a form of cancer [17]

Upper and lower human gastrointestinal tract. The esophagus (American English), oesophagus (British English), or œsophagus (archaic spelling) (see spelling difference) all / iː ˈ s ɒ f ə ɡ ə s, ɪ-/; [1] pl.: ((o)e)(œ)sophagi or ((o)e)(œ)sophaguses), colloquially known also as the food pipe, food tube, or gullet, is an organ in vertebrates through which food passes, aided by ...
Micrograph of Barrett's esophagus (left of image) and normal stratified squamous epithelium (right of image). Alcian blue stain. Glandular metaplasia is a type of metaplasia where irritated tissue converts to a glandular form. An example occurs in the esophagus, where tissue becomes more similar to the tissue of the stomach.
