| Barrettīs epithelum - short segment |
 |
Barrettīs mucosa is a
metaplastic
columnar epithelium, that has replaced the native squamous cells
at the
esophagocardial junction.
Itīs thought to provide
greater resistance to gastroesophageal reflux, which
in turn
is discussed to be causative. The
left picture shows these dark red,
finger- like epithelial islands amidst
the normal, uninflammed, whitish,
squamous epithelium.
Since Barrettīs esophagus is a precancerous lesion,
it needs regular
biopsy.
