Histopathological Implications of Aspergillus Infection in Lung
Figure 1
Invasive pulmonary aspergillosis, discrete nodule. (a) The nodule comprises coagulation necrosis of the lung tissue () and acute hemorrhage usually accompanies the necrosis () and may mimic a halo sign on CT (Hematoxylin-Eosin, X20). (b) Zone formation (mimicking an annual ring) of hyphae aligned in a radial pattern. Few inflammatory infiltrates are accompanied in the lesion (Hematoxylin-Eosin, X200). (c) Acute hemorrhage can be seen. No hyphae can be observed.
