<prompt> A liver biopsy reveals following findings. What is true about this conditionNodular regenerative hyperplasia of liver induced due to OCPNutmeg liver with dark areas of perivenular dead hepatocytes and gray areas of periportal viable hepatocytesNutmeg liver with pale areas of necrosis and dark congested areas of perivenular viable hepatocytesCirrhotic liver with fibrotic nodules.  <response>: This is a classical picture of nutmeg liver seen in chronic passive venous congestion on the liver.The dark congested areas consist of necrotic hepatocytes while the surrounding paler and brownish appearing regions are viable hepatocytes.The combination of hypoperfusion and retrograde congestion acts synergistically to cause centrilobular hemorrhagic necrosis.The liver takes on a variegated mottled appearance, reflecting haemorrhage and necrosis in the centrilobular regions.This finding is known as nutmeg liver due to its resemblance to the cut surface of a nutmeg. Robbins 9e p864 Passive Congestion and Centrilobular Necrosis Hepatic manifestations of systemic circulatory compromise-passive congestion centrilobular necrosis can be seen in both left right-sided heart failure.PathologyRight-sided cardiac decompensation leads to passive congestion of the liver.The liver is slightly enlarged, tense, and cyanotic, with rounded edges.Microscopically there is congestion of centrilobular sinusoids.With time, centrilobular hepatocytes become atrophic, resulting in markedly attenuated liver cell plates.Left-sided cardiac failure or shock may lead to hepatic hypoperfusion hypoxia, causing ischemic coagulative necrosis of hepatocytes in the central region of the lobule centrilobular necrosis. Combination of hypoperfusion retrograde congestion acts synergistically to cause centrilobular hemorrhagic necrosis.The liver takes on a variegated mottled appearance, reflecting hemorrhage necrosis in the centrilobular regions.This finding is known as nutmeg liver due to its resemblance to the cut surface of a nutmeg.
