    Tinea nigra: report of twelve cases in Venezuela.
    Mycopathologia 2005 Oct;160(3):235-8
    Sección de Micología Médica, Instituto de Medicina Tropical, 1041 Caracas, Venezuela.
    Tinea nigra is a superficial mycotic infection produced by Hortaea werneckii, formerly known as Phaeoannelomyces werneckii, formerly known as Exophiala werneckii, and Stenella araguata, the latter autochthonous in Venezuela, it was first described and named as Cladosporium castellanii in 1973. The present report describes 12 cases in the period of 1972-2002, diagnosed at the Medical Mycology Section at the Tropical Institute of the Universidad Central de Venezuela, in Caracas. This mycosis is more prevalent among young people, with fair skin, from 3 to 28 years of age, who visited beaches and in whom the lesions are more evident. Out of these 12 patients, 8 (66.66%) had Phaeoannelomyces werneckii as the causal agent and 2 (16.67%) Stenella araguata was isolated. Two patients had more than one macule, and curiously in these cases, each lesion was caused by a different species of the aforementioned fungus.

    Tinea nigra, a relatively uncommon mycosis caused by Phaeoannelomyces werneckii, is typically seen as an asymptomatic brown or black macule on the hands and feet. We present two cases of tinea nigra in children in São Paulo, Brazil, and alert readers to the potential for confusion with melanocytic lesions. Read More

    Hortaea werneckii, a black yeast-like hyphomycete that is widely distributed in tropical and subtropical environments, can cause superficial mycotic infection in humans. This fungus was recently isolated from superficial infectious lesions of a guinea pig in Japan. An oligonucleotide primer set specific for Hortaea werneckii was designed on the basis of the internal transcribed spacer regions of the ribosomal DNA (rDNA). Read More

    Tinea nigra is an asymptomatic superficial fungal infection caused by Phaeoannelomyces werneckii, generally affecting the skin of the palms and characterized by deeply pigmented macular non-scaly patches. These lesions are quite characteristic. However, they can be misdiagnosed as a malignant melanoma or a junctional melanocytic nevus and unnecessary biopsies may be performed. Read More

    We report a case of tinea nigra on the left palm of a 13-year-old girl. She had noticed a pigmented, asymptomatic macule on the left palm approximately 4-5 years prior to her first visit to our hospital. The color of the lesion tended to change before and after a bath; it became lighter after a bath and darkened some time later. Read More
