Scytalidium hyalinum infection of skin and nails

Five cases of skin and nail infection associated with Scytalidium hyalinum are described. The lesions were confined to the hands, feet and toenails. All the patients were from the West Indies and were of Negroid descent. Scytalidium hyalinum was the only fungus isolated on repeated culture from three patients, while the remaining two patients had mixed infections, one with Trichophyton mentagrophytes var. interdigitale and the other with Hendersonula toruloidea.
