Morphology: Panlobular giant cell transformation of hepatocytes and formation of hepatocyte "rosettes"

Neonatal Cholestasis(TOPNOTCH)


Morphology: characterized by coarse fibrous septae that subdivide the liver in a jigsaw like pattern

Secondary biliary cirrhosis(TOPNOTCH)


Morphology: florid duct lesion

Primary Biliary Cirrhosis(TOPNOTCH)


The combination of hypoperfusion and retrograde congestion acts synergistically to generate what type of necrosis in the liver?

Centrolobular hemorrhagic necrosis(TOPNOTCH)


Morphology: periportal sinusoids contain fibrin deposits with hemorrhage into the space of Disse, leading to periportal hepatocellular coagulative necrosis



Type of liver transplant rejection : severe obliterative arteritis of small and larger arterial vessels results in ischemic changes in the liver parenchyma

Chronic Rejection(TOPNOTCH)


Type of liver transplant rejection: infiltration of a mixed population of inflammatory cells into portal tracts, bile ducts, and hepatocyte injury and endothelitis

Acute cellular rejections(TOPNOTCH)


What do you call the small tubular channels that are sometimes burried within the gallbladder wall adjacent to the liver?

Ducts of Luschka(TOPNOTCH)


What is the most common congenital anomaly seen in the Gallbladder?

A folded fundus or so called phrygian cap(TOPNOTCH)


Gross morphology: the mucosal surface of the gallbladder is studded with minute yellow flecks

Strawberry Gallbladder(TOPNOTCH)


What type of pigment stones are generally seen in infected intrahepatic or extra hepatic ducts?

Brown pigment stones(TOPNOTCH)


Gross morphology: GB is shrunken, nodular, and chronically inflamed with foci of necrosis and hemorrhage

Xanthogranulomatous cholecystitis(TOPNOTCH)
