Cholangiocarcinoma is a cancer of the biliary tree; a system of ducts that carries bile from the liver to the small intestine where it is used to aid in digestion.
In image 2, the ducts, which appear as large circular structures, are disorganized with irregular lumens. The nuclei of their cells, which appear as smaller dark purple structures, show variation in shape and size when in normal ducts they should be the same size and shape. In image 3, the ducts are again disorganized. In this image, mucinous secretions are more evident than in image 2.

Amyloid deposits are insoluble collections of misfolded proteins. These misfolded proteins can be involved in a number of disease processes including amyloidosis, Alzheimer’s disease, rheumatoid arthritis and many more.
In this image, the amyloid deposits are highlighted by a special stain called Congo Red which gives them a bright red-orange color under standard microscopy. Under polarized light the amyloid will have an apple-green color.
