Lab 1b Chronic
Pancreatitis continued (59000-43000)
Slide 4
This is a low magnification
picture of the H&E slide of chronic pancreatitis in your class
set. This particular patient had an obstructive type of pancreatitis
due to carcinoma of the head of the pancreas. The lobular
architecture of the pancreas is accentuated by the broad bands of
interstitial fibrosis.

Slide 5
The fibrous scarring of the pancreas is highlighted with the
Trichrome stain. The fibrous septa appear as blue bands surrounding
the residual pancreatic lobules, which stain red.

Slide 6
Shows the dense interstitial fibrosis
surrounding two pancreatic lobules. Note there is also an increase
in intralobular fibrous tissue and there is chronic inflammation.
|
 |
Slide 7
The
exocrine portion of the gland is most severely affected. There is
almost total atrophy and fibrous replacement of pancreatic acini
with relative preservation of the pancreatic ducts and islets of
Langerhans (arrows). The intralobular pancreatic ducts are
irregularly shaped and are embedded in chronically inflamed fibrous
tissue. Several preserved islets are marked with arrows.
