Facial Phaeohyphomycosis in an Immunocompetent Individual: A Rare Presentation of a Rare Fungus

Abstract: Phaeohyphomycosis is a rare mycotic infection caused by heterogenous groups of dematiaceous fungi involving the skin and subcutaneous tissue. Here, we report a case of cutaneous phaeohyphomycosis presenting as cauliflower-like verrucous lesion over the face in an immunocompetent individual. Histopathology showed suppurative granulomatous inflammation replete with pigmented broad fungal hyphae which is stained with periodic acid–Schiff stain, Grocott's methanamine silver stain, Schmorl's stain, and Masson-Fontana stain. Culture showed black-colored colonies identified as Exophiala spinifera.
