Cytomorphology of Aspergillus in sputum and bronchial brushing samples processed using the SurePath LCT platform or conventional cytopathology, followed by PAS staining. The mycelium of Aspergillus appeared magenta after PAS staining. Magnification, 400X. (A) Conventional PAS on sputum samples; (B) LCT-based PAS on sputum samples; (C) Conventional PAS on bronchial brushing samples; (D) LCT-based PAS on bronchial brushing samples. LCT: Liquid-based cytopathology; PAS: Periodic Acid-Schiff.
