Slide 115: Biliary obstruction secondary
to pancreatic carcinoma
 |
Here you see the area of tumor
causing compression of the bile ducts resulting in the bile stasis.
See this slide with the
virtual microscope. |
 |
You won't see any cancer
in this picture. The malignancy is down in the lower end of the biliary system.
You will see the bile ducts and canaliculi plugged with a glassy brown
or deep red staining material. This is the inspissated bile. There will
likely be some inflammation in the triads. The "clearing or halo" effect
you will see around some of the bile ducts is an artifact of fixation,
and not the pathology we are referring to. I have indicated an example
on the picture. |
