case_images: Histopathology of the lung. A. Numerous hyphae and fungal spores shown by H&E staining. Microscopic cavitation surrounded by numerous hypahes and fungal spores (40x). B. Well-defined Aspergillus head, allowing the visualization of phialides and conidia, with numerous fungal spores (PAS, 400x). C. Well-defined aspergillary structure showing conidiophore, aspergillary vesicle, phialides, and conidia, as well as several hyphae of regular diameter, some with septations and dichotomous branches (Gomori-Grocott, 400x). D. Bronchopneumonia with alveoli filled by neutrophils (H&E, 400x). E. Fibrin thrombi occluding a medium-sized artery (H&E, 400x) F. Squamous metaplasia in alveolar epithelial cells (H&E, 400x).

case_images: Microscopic visualization of the lung showed the presence of clearly defined Aspergillus structures, including hyphae and fungal spores, and a well-defined Aspergillus head with phialides, conidia, and spores, as well as bronchopneumonia, fibrin thrombi occluding an artery, and squamous metaplasia (Figure 1).
