Liver Path 3 - Nelson Flashcards
What characterizes pre-eclampsia?
What is HELLP syndrome?
Maternal hypertension, proteinuria, peripheral edema, and coagulation abnormalities
Preeclampsia can sometimes become severe and then manifest HELLP syndrome. Hemolysis Elevated Liver-enzymes Low Platelets
Acute Fatty Liver of Pregnancy is characterized by acute onset of liver dysfunction. What do you see on liver biopsy?
Microvesicular steatosis
Same thing you see in liver of Reye Syndrome
Most common benign neoplasm of the liver:
Hemangioma
What is the name of the congenital dilatation of the common bile duct? What patients does it happen to?
Choledochal cyst
Occurs in kids
What is caroli’s disease?
Intrahepatic biliary dilatation, which communicates with biliary tree
(A few different congenital disorders fall under this disease’s umbrella
This lesion is composed of a proliferation of all liver parenchymal elements. Imaging studies will show a central stellate scar.
What is it?
Focular Nodular Hyperplasia
This lesion is a well-circumscribed benign neoplasm. Lack of portal triads and central veins will help you see it’s not normal liver. It’s more common in young reproductive age females taking oral contraceptives.
Hepatocellular Adenoma
Most important factors disposing to HCC (hepatocellular carcinoma) are Chronic Viral Hepatitis and toxin exposure. What is the differences between major risk in the U.S. vs major risk in China/SE Asia?
Chronic hepatitis from HBV and HCV have very big risk.
Aflotoxin (mld toxin growing on nuts) is major toxin
In U.S. -> it usually stems from cirrhosis
Cholangiocarcinomas are carcinomas arising from intra- or extra-hepatic bile ducts. Tumor nodules are usually white and hard. It is associated with liver flukes, PSC, Caroli’s Disease, Congenital Hepatic fibrosis, choledochal cysts, viral hepatitis and NAFLD. What neoplastic lesion would have to be excluded to make the dx or cholangiocarcinoma?
Exclude Adenocarcinoma metastasis to the liver.
Four F’s of gallstones?
And other risk factors?
Female, Forty, Fat, Fertile
rapid weight loss, pregnancy, oral contraceptives (progesterone decreases gall-bladder smooth muscle tone in pregnancy)
When you think about acute cholecystitis, you should think about what kin of inflammation?
Neutrophilic
Neutrophils! Neutrophils!
Stones in common bile duct:
Choledocholithiasis!
When you think about chronic cholecystitis, you should think about what kind of inflammation?
Chronic lymphocytic inflammation
also fibrosis
Why are pigment stones more common in Eastern Asia as opposed to the cholesterol stones more commonly seen in W. Europe and the Americas?
In E Asiathere is an increase in bacterial/parasitic biliary infections which are associated with the pigmented stones.
What type of cholangiocarcinoma arises at comfluence of R and L hepatic ducts?
Klatskin tumor
or
Perihilar cholangiocarcinoma
