A 63-year-old man comes to the physician for
a follow-up evaluation of chronic, retrosternal chest pain. The pain
is worse at night and after heavy meals. He has taken medicines to reduce the
production of stomach acids for several months without any relief from his symptoms.
An upper endoscopy shows changes in the distal
esophagus and in the area above the gastro-oesophageal junction. A biopsy
of the distal esophagus shows simple columnar epithelium with goblet
cells, which does not occur normally here. Which type of epithelium should
normally occur here?
