Microscopic findings. A parenchymal extinction lesion is seen, defined as the approximation of portal tract and hepatic vein due to the loss of intervening hepatocytes (A). The hepatocyte plates are disrupted (A, lower half). Macrovesicular and microvesicular steatosis is also seen (A, upper half). Sinusoidal dilatation is seen in the centrilobular area (B), and is accompanied by erythrocyte extravasation and congestion (C). Obliteration of a terminal hepatic venule is seen (D) (A-D, Masson's trichrome).
