Histopathological examinations in patient with invasive pulmonary aspergillosis presenting discrete nodule. (A) The pilcrow (¶) and the section signs (§) are placed on the areas of monotonous high density and peripheral reticular structure on computed tomography image, respectively. The area of monotonous high density nodule (¶) comprised coagulation necrosis with remaining alveolar septa and without air content due to inflammatory exudation. The necrosis was surrounded by alveoli filled with oozing (§) (Photomicrographs stained with hematoxylin and eosin (HE) double stain and scale bar represents 1000 μm). (B) High-power field of peripheral oozing of red blood cell (Photomicrographs stained with HE double stain and scale bar represents 100 μm).
