Arch Derm Syphilol. 1947;56(6):834-845. doi:10.1001/archderm.1947.01520120122014

LOCALIZED dermatomycosis involving limited areas of the skin, especially of the feet, is one of the commonest cutaneous diseases. Statistics indicate that in the United States the incidence of fungous infections of the feet in large cities reaches 30 to 90 per cent of the adult population, with a higher incidence in the southern than in the northern part of the country. In spite of this high incidence, cases of more generalized dermatomycoses, affecting large areas of the skin of the trunk and of the extremities, are relatively rare. In general the widespread eruptions are caused by the same species of fungi which are responsible for the more localized forms. Unusually extensive involvement of the skin may be due to several factors, which may include either an exceptional vitality and pathogenicity of a particular strain of fungus or an abnormality of the skin itself which makes it an especially favorable
