Nasal phaeohyphomycosis caused byBipolaris hawaiiensis

Abstract

A bilateral nasal phaeohyphomycotic infection caused by Bipolaris hawaiiensis in an immuno-compromised woman from India is described. Repeated direct microscopic examinations of the nasal scrapings revealed the presence of septate, branched, pigmented hyphal fragments intermingled with cells that divided internally by one transverse septum and a few cells that were chestnut brown dividing internally by septa in different planes to become muriform. Cultures of the scrapings yielded B. hawaiiensis. Local excision of the crusted lesion followed by application of 0.03% nystatin solution four times a day for 3 weeks cured the infection.
