Nigrospora is rarely an opportunistic pathogen in humans. To our knowledge, there have been 4 reports on Nigrospora-induced human eye and skin infections in the literature.1- 3 However, none of these cases included definite clinicopathologic evidence or species identification. Herein, we report the first case to our knowledge of Nigrospora sphaerica–induced onychomycosis in humans.
