ously known as Scytalidium dimidiatum) as possible pathogens. The latter is considered an emerging fungus of the dematiaceous family, which causes chronic cutaneous and nail lesions, and may even invade deeper tissues. This report describes a case of superficial black onychomycosis caused by Neoscytalidium dimidiatum, demonstrating the importance of including this organism in the differential diagnosis for pigmented nail lesions that can mimic melanoma. Simple semiological and complementary methods can support or confirm the diagnosis of black onychomycosis.
