Ans is D. Adenocarcinoma
(Condition shown: Barrett’s esophagus)
Barrett’s esophagus
- It refers to an abnormal change (metaplasia) in the cells of the lower portion of the esophagus.
- It is characterized by the replacement of the normal stratified squamous epithelium lining of the esophagus by simple columnar epithelium with goblet cells (which are usually found lower in the gastrointestinal tract).
- The medical significance of Barrett’s esophagus is its strong association with esophageal adenocarcinoma, because of which it is considered to be a premalignant condition.
- The main cause of Barrett’s esophagus is thought to be an adaptation to chronic acid exposure from reflux esophagitis.
