Barrett食管:胃食管交界处上方有胃黏膜上皮(柱状上皮)


Barrett食管,多见于慢性返流性食管炎。胃食管交界处上方有胃黏膜上皮(柱状上皮)。左为柱状上皮,右为鳞状上皮。图示典型的Barrett食管黏膜,因有肠上皮化生(柱状上皮内也可见杯状细胞。)
Another cause for inflammation is a so-called "Barrett's esophagus" in which there is gastric-type mucosa above the gastroesophageal junction. Note the columnar epithelium to the left and the squamous epithelium at the right. This is "typical" Barrett's mucosa, because there is intestinal metaplasia as well (note the goblet cells in the columnar mucosa).
