title: Tinea nigra: report of twelve cases in Venezuela.
abstract: 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.
