Flashcards in XVI - The Liver, Gallbladder and Biliary Tree Deck (102)
Morphology: Panlobular giant cell transformation of hepatocytes and formation of hepatocyte "rosettes"
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
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
What type of pigment stones are generally seen in infected intrahepatic or extra hepatic ducts?
Brown pigment stones(TOPNOTCH)
