[Aspergillus mycetoma of the maxillary sinus]

The author describes a new case of aspergillosis in maxillary antrum, treated by surgery. A particularity of this case was an eosinophilia that disappeared after the treatment. Correlation with fungus infection was made probable by presence of a great amount of eosinophilic blood cells in hyperplastic mucosa involving the lesion. A review is made of literature.
