ABSTRACT

Neoscytalidium dimidiatum is a filamentous, dark and keratinolytic fungus, a recognized agent of onychomycosis and superficial skin infections known as scytalidiosis. It has also been described as responsible for endophthalmitis, sinusitis, osteomyelitis, mycetomas, invasive cerebral feohifomicosis and disseminated infections in immunosupressive patients. The first case of dermatomycosis due to N. dimidiatum diagnosed in Naranjo Health Area, Alajuela, Costa Rica, a tropical and traditionally agricultural climate zone is presented.
