Abstract Tinea nigra palmaris, a chronic superficial mycosis caused by Cladosporium wernecki, is frequent in South America,1 but has been reported in only four white North Americans. Three of these cases were in white men who contracted the disease while working in Panama.2 The fourth patient was a white girl, a resident of Florida, who had been infected at 12 years of age.3 Inasmuch as we have been unable to locate further records of the occurrence of this fungous infection in the United States, it was thought of interest to present an additional case, which is also unusual because of the youth of the subject. REPORT OF A CASE A white boy, aged 3½ years, was first seen in July, 1954, presenting on the right palm two small dirty plaques of two months' duration. Each lesion measured about 1 cm. in diameter, was fairly well demarcated, and References 1. Aroeira Neves, J., and Costa, O. G.: Tinea Nigra , Arch. Dermat. & Syph. 55:67, 1947. 2. Walsh, E.
