Morphological characteristics of Aspergillus in the BAL fluid sample prepared by LCT, followed by special staining. Typical cytological characteristics of aspergillus filament include filament separation, uniform in size, and parallel in wall, with dichotomous branching at acute angles. Magnification, 40x. (a) Magenta filament of LCT in the BAL fluid sample by PAS. (b) Brown-black filament of LCT in the BAL fluid sample by GMS. BAL: bronchoalveolar lavage; LCT: liquid-based cytopathology; PAS: periodic acid-schiff; GMS: grocott’s methenamine sliver.
