Description

We report an autopsy case of Aspergillus brain abscess that had extended from Aspergillus sinusitis, and attempted to detect the fungus in cytology specimens byFungiflora Y® and Papanicolaou double staining. An 80-year-old man was found to have right orbital and sphenoidal aspergillosis. Treatment with antifungal agents was ineffective, and a brain abscess was detected by magnetic resonance imaging seven months later. The patient's condition deteriorated and he died. Pus from the brain abscess was used to makes smear and Fungiflora Y®-Papanicolaou double staining was performed. It was difficult to detect the fungi on screening with the ×10 objective lens of light microscope because of their faint color. However, under a fluorescence microscope the fungal hyphae were apple green and it was very easy to detect them. Thus, Fungiflora Y®-Papanicolaou double staining seems very useful for detecting fungal hyphae on smear cytology.
