Slide 19: Acute Erosive Esophagitis
 |
Your slide shows almost
a complete cross section of the esophagus. Note there are several
areas of mucosal ulceration and some relatively large, thin walled vessels
are present in the lamina propria.
See this slide with the
virtual microscope. |

This is a higher power
view of the base of the ulcer. You will see a mixed acute and chronic inflammatory
infiltrate in association with the elements of granulation tissue. You
should be able to identify both angioblasts and reactive fibroblasts in
the base of the ulcer. Remember that even though this is referred to as
"acute" esophagitis, there will always be a few lymphocytes involved in
the repair process. One practically never sees a pure acute or chronic
infiltrate. Also, in this case the injury is one of duration, so some element
of a chronic response would be expected. |
