Paranasal Sinus Phaeohyphomycosis: A Case Report and Literature Review

Abstract

Fungal infections of the paranasal sinuses manifest from simple colonization (Eg: fungal ball) to invasive forms (Eg: Rhizopus: Mucor) depending on the immune status of the host. Infection with lesser-known species like dermatophyseal fungus has been rarely reported in the literature. We report a rare case of Paranasal sinus phaeohyphomycosis in a 30-year-old immunocompetent male presenting to our tertiary care centre with right cheek swelling of 1-year duration with CT showing homogeneously enhancing soft tissue density in the right maxillary sinus with erosion of the anterolateral wall. FNAC revealed pseudo septate, bulbous pigmented fungal hyphae which resolved with surgical debridement and antifungal therapy for 6 weeks.
