ABSTRACT

Black fungal onychomycosis also known as pheohifomycosis of the nail, is part of the condition called fungal melanonychia, which has been known for several years. The etiologic agents of this infection are black or demataceous fungi, which usually act as opportunistic pathogens causing invasion and infection, taking advantage from a predisposing factor. It has a universal distribution and is endemic in several countries. It can be found in different climates and ecosystems. This type of fungi has specific pathogenicity factors that make it easier for them to develop in the host. Affected patients may have a variable spectrum in the clinical presentation of nail pathology, which is important to know so that an appropriate differential diagnosis is made with other pathologies both benign and malignant. Currently, for the diagnosis of this type of onychomycosis, it is required to have a direct microscopic observation, cultures in unconventional media and a high clinical suspicion. With regard to antifungal therapy, it is known to be exceptionally difficult and that this kind of fungi have a poor response to the antifungals that are used nowadays.
