Overview
Skin biopsy may be helpful in the diagnosis of cutaneous aspergillosis.[1][2]
Other Diagnostic Studies
Skin Biopsy
- Skin biopsy is helpful in the diagnosis of cutaneous aspergillosis.
- Histopathologic examination with hematoxylin and eosin will variably demonstrate Aspergillus hyphae.[2]
- The Gomori methenamine silver stain, however, clearly detects hyphae, since the hyphal cell wall stains black, while the background tissue stains green.
- Aspergillus hyphae should have acute-angle branching and frequent septations on histopathological examination.
