Cholangiocarcinoma (primary sclerosisng cholangitis) (TOPNOTCH)Robbins Basic Pathology, 8th ed, p 659
A 30 year old male with inflammatory bowel disease develops jaundice. On hepatic ultrasound, there are strictures and beading of the large bile ducts, and pruning of the small bile ducts. A liver biopsy showed portal tracts with concentric periductal onion-skin fibrosis, and a modest lymphocytic infiltrate. SEE SLIDE 16.18. In five years, he has a 10 to 15% chance of developing (A) colorectal carcinoma (B) hepatocellular carcinoma (C) cholangiocarcinoma (D) hepatic lymphoma

all of the above (TOPNOTCH)Robbins Basic Pathology, 8th ed, p 671
Which of the following is a risk factor for the development of cholangiocarcinoma? (A) primary sclerosing cholangitis (B) exposure to the radiologic agent Thorotrast (C) infection with Clonorchis (D) all of the above
142
Gilbert Syndrome (TOPNOTCH)Robbins Basic Pathology, 9th ed, p 606
Cause of hyperbiliribunemia that is due to an inborn mutation of the gene encoding glucuronosyltransferase, which leads to decreased levels of this enzyme.
143
Hemolytic anemias (TOPNOTCH)Robbins Basic Pathology, 9th ed, p 606
Most common cause of jaundice with an UNconjugated hyperbilirubinemia picture
144
Acute hepatitis has LESS inflammation and more hepatocyte death than hepatitis. Chronic hepatitis has DENSE mononuclear portal infiltrates and in time, fibrosis. The type of inflammatory cell is not useful because they all invoke a T cell-mediated immunity (mononuclear infiltrates, usually), unlike in other tissues where acute usually has neutrophils (TOPNOTCH)Robbins Basic Pathology, 9th ed, p 606
Key difference between acute hepatitis and chronic hepatitis
145
4% (TOPNOTCH)Robbins Basic Pathology, 9th ed, p 615
Among those acutely infected with hepatitis B, what percentage will progress to chronic hepatitis B?
146
20-30% (TOPNOTCH)Robbins Basic Pathology, 9th ed, p 615
Among those with chronic hepatitis B, how many will progress to cirrhosis?
147
2.5% (TOPNOTCH)Robbins Basic Pathology, 9th ed, p 615
Among those with cirrhosis due to chronic hepatitis B, what is the risk per year of developing hepatocellular carcinoma?
148
85% (TOPNOTCH)Robbins Basic Pathology, 9th ed, p 615
Among those acutely infected with hepatitis C, what percentage will progress to chronic hepatitis C?
149
20% (TOPNOTCH)Robbins Basic Pathology, 9th ed, p 615
Among those with chronic hepatitis C, how many will progress to cirrhosis?

There is an early phase of severe cell injury and inflammation followed by RAPID SCARRING. In viral heaptitis, fibrosis takes years or decades to accumulate. There is also an abundant PLASMA CELL infiltration in autoimmune hepatitis. SEE SLIDE 16.19. (TOPNOTCH)Robbins Basic Pathology, 9th ed, p 615
How does one differentiate autoimmune hepatitis from viral hepatitis histologically?
151
FATTY Liver disease (Specifically, alcoholic fatty liver disease) (TOPNOTCH)Robbins Basic Pathology, 9th ed, p 622
Pattern of scarring is distinctive in this liver disease. It starts with central vein sclerosis, then moves outward in a chicken wire fence pattern, creating a central-portal fibrous septa. Ultimately leads to the classic micronodular or Laennec cirrhosis.

Primary Biliary Cirrhosis (PBC) (TOPNOTCH)Robbins Basic Pathology, 9th ed, p 627
PRIMARY BILIARY CIRRHOSIS or PRIMARY SCLEROSING CHOLANGITIS: Usually female
153
Primary Biliary Cirrhosis (PBC) (TOPNOTCH)Robbins Basic Pathology, 9th ed, p 627
PRIMARY BILIARY CIRRHOSIS or PRIMARY SCLEROSING CHOLANGITIS: Strong association with Sjogren Syndrome

Primary Sclerosing Cholangitis (PBC) (TOPNOTCH)Robbins Basic Pathology, 9th ed, p 627
PRIMARY BILIARY CIRRHOSIS or PRIMARY SCLEROSING CHOLANGITIS: Strong association with IBDs like Crohn and Ulcerative Colitis

Primary Biliary Cirrhosis (PBC) (TOPNOTCH)Robbins Basic Pathology, 9th ed, p 627
PRIMARY BILIARY CIRRHOSIS or PRIMARY SCLEROSING CHOLANGITIS: Strong association with anti-mitochondrial antibody
156
Primary Biliary Cirrhosis (PBC) (TOPNOTCH)Robbins Basic Pathology, 9th ed, p 628
PRIMARY BILIARY CIRRHOSIS or PRIMARY SCLEROSING CHOLANGITIS: Histology shows FLORID DUCT LESIONS (inflammation of interlobular biled ducts). SEE SLIDE 16.20. Thereafter, nodular regerative hyperplasia (vague nodularity that differs from cirrhosis) and overt cirrhosis with periportal cholestasis and feathery degeneration may develop.
157
Primary Sclerosing Cholangitis (PBC) (TOPNOTCH)Robbins Basic Pathology, 9th ed, p 628
PRIMARY BILIARY CIRRHOSIS or PRIMARY SCLEROSING CHOLANGITIS: Histology may show circumferential fibrosis (onion skinning) in small ducts that leads to the diagnostic TOMBSTONE SCAR (dense button of scar tissue). SEE SLIDE 16.18. There may also be biliary intrapethelial neoplasia, which is a harbinger of cholangiocarcinoma.
158
Primary Sclerosing Cholangitis (PBC) (TOPNOTCH)Robbins Basic Pathology, 9th ed, p 628
PRIMARY BILIARY CIRRHOSIS or PRIMARY SCLEROSING CHOLANGITIS: Associated with strictures and beading of large bile ducts. SEE SLIDE 16.18.
