Demodex mite infestation of unknown significance in a patient with rhinocerebral mucormycosis due to Apophysomyces elegans species complex.

Demodex mites have been reported in the past as a cause of facial rash in immunosuppressed patients. Here, we report an interesting case of possible demodicosis associated with rhinocerebral mucormycosis. The association of mites with a fungus was detected on direct microscopic examination of the scrapings of a nasal ulcer. The mite and the fungus were identified as Demodex folliculorum and Apophysomyces elegans species complex, respectively.
