Intestinal metaplasia
Abnormal transformation of bodily tissue into intestinal tissue
Intestinal metaplasia is the transformation (metaplasia) of epithelium into a type of epithelium resembling that found in the intestine. In the esophagus, this is called Barrett's esophagus. Chronic inflammation caused by H. pylori infection in the stomach and GERD in the esophagus are seen as the primary instigators of metaplasia and subsequent adenocarcinoma formation. Initially, the transformed epithelium resembles the small intestine lining; in the later stages it resembles the lining of the colon. It is characterized by the appearance of goblet cells and expression of intestinal cell markers such as the transcription factor, CDX2.
