Note the prominent congested septal capillaries and the faint staining edema fluid filling alveolar spaces
Pulmonary edema; a case of Lt heart failure
Chronic venous congestion (CVC) lung: low power (Lt) and high Power (Rt) views. Note: 1. engorgement of septal capillaries 2. hemosiderin-laden macrophages (the hemosiderin granules within cytoplasm of macrophages appear brownish)
CVC lung
cut surface shows mottled appearance; the dark areas represent congestions around central veins. This altration has been likened to the cut surface of a nutmeg “nutmeg liver”. Chronic venous (passive) congestion liver
The centrilobular area shows accumulation of blood with damage to the centrilobular liver parenchyma. The portal tract and surrounding periportal parenchyma, however, are relatively spared.
