14. Infarct of the Lung - High Power
Note that the outlines of the pulmonary alveoli can be seen but the structural details have been obscured in this area of coagulative necrosis. There are no intact nuclei. The pulmonary airspaces seem filled with debris, derived in this case from remnants of red blood cells, i.e., there was hemorrhage in this area of necrosis.
