Abstract:
Parathyridaria percutanea is an unusual fungus causing subcutaneous phaeohyphomycosis in India. A 74-year-old female presented with multiple swellings on the dorsum of her left hand for 6 months. The patient does not have Diabetes mellitus, is not immunocompromised, and does not have any other co-morbidities. Histopathological stains showed fungal hyphae in the epidermis and dermis. On the KOH mount, phaeoid fungal hyphae were observed. On culture, cream to grey fungal growth was observed, which was non-sporulating. This was identified as Parathyridaria percutanea by sequencing. Molecular techniques are an important diagnostic tool for the accurate identification of these unusual fungal isolates.
