ABSTRACT

White piedra is a superficial mycoses characterized by nodules on the hair shaft, caused by the basidiomycetous yeasts. In the present study, clinical and mycological findings of scalp white piedra caused by Trichosporon spp. are related. Twenty three cases of scalp white piedra were observed with a high incidence in women (87 percent) and preschool children from 2 to 6 (74 percent) years old. These groups presented a relationship of dependence with this infection. Despite the low socio-economic status, poor standards of hygiene, (48 percent of the patients) as well as the fact that 30.4 percent of the children shared the same nursery, these factors were not significant for the transmission of the mycosis. These were the first reports of scalp white piedra in Joäo Pessoa city, Paraíba, Brazil

ABSTRACT

Espécies de Trichosporon foram isoladas em 9 (7,2 porcento) dos 125 pacientes HIV positivo. Colonizaçäo anal foi observada em 5 (4 porcento) destes pacientes. T. inkin foi isolado da regiäo anal de dois homens bissexuais e de um homossexual e T. asahii de um homem bissexual e de uma mulher heterossexual. Piedra gênito púbica foi observada em 5 (5,6 porcento) dos 90 homens. T inkin foi agente de 4 (7,5 porcento) casos de piedra branca no grupo de 53 homens homo/bissexuais e T. asahii foi responsável por um (2,7 porcento) caso em heterossexual. A identificaçäo em nível de espécie foi essencial para diferenciaçäo das espécies: T inkin e T. asahii que colonizaram a regiäo anal e foram agentes de piedra branca gênito púbica em pacientes HIV positivo
