Isolated frontal sinusitis due to Pseudallescheria boydii.

ABSTRACT

We report a case of recurrent sino-nasal fungal infection due to Pseudallescheria boydii (P. boydii) in a 33-year-old diabetic woman. It is very essential to identify P. boydii, as Miconazole is the only antifungal drug of choice. However, histological examination of the specimen for clinching clues such as intercalary conidia and chlamydoconidia plays an important role in identifying P. boydii, when fungal culture fails to yield the growth. On follow-up, the woman responded for the treatment with Miconazole and is free of symptoms, with no recurrence after 6 months.
