116b cirrhosis and liver cancer Flashcards
what can cause liver cirrhosis? what is the appearance of the cirrhosis?
alcohol –> micronodular (no triads/central veins)
Hep B and C –> macronodular (contains vessels)
toxins - hemochromatosis, wilson’s, A1AT deficiency
long term outcomes of cirrhosis? reversible?
portal HTN
HCC
irreversible
what is the pathogenesis of cirrhosis?
inflammation, cell necrosis –> scars (stellate cells), regeneration –> disortion –> functional problems with blood flow (portal HTN)
Budd-Chiari syndrome
hepatic vein/IVC occlusion/thrombosis
from hypercoagulable state (lupus, prergo), HCC
leads to hepatomegaly, abd pain, ascites
liver failure from cirrhosis - endocrine problems
feminization due to increased conversion of testosterone to estrone)
spinder angiomas
gynecomastia
testicular atrophy
markers of HCC
increased a-fetoprotein (>500)
enlarged liver/mass - repeat US/repeat biopsy
elevation of right diaphragm
malig epithelial liver tumors
HCC - liver cell
cholangiocarcinoma - bile duct cell
malig non-epithelial liver tumor
angiosarcoma
Hepatic adenoma
Benign liver tumor
often related to oral contraceptive or steroid use
circumscribed w/out cirrhosis
can regress spontaneously.
