[Contribution to the morphologic diagnosis of lung adiaspiromycosis]

The diagnosis of adiaspiromycosis is usually based on lung sections stained by hematoxylin-eosin, periodic acid Schiff and methenamine silver. Authors describe the fungus aspect examined by mucicarmin, picro-sirius and Congo red methods, including polarized light microscopy. In doubtful cases, these methods could contribute to histopathological diagnosis of Emmonsia parva var crescens.
