Dermatoses associadas às leveduras do gênero malassezia / Dermatosis associated with yeasts from Malassezia genus

A importância das leveduras do gênero Malassezia vem aumentando a partir do seu reconhecimento enquanto importantes patógenos em pacientes com algum tipo de imunodepressão. O esforço na identificação de novas espécies decorre da necessidade de entendimento mais abrangente da patogênese das dermatoses a elas associadas. A nova taxonomia dessas leveduras e todas as dermatoses a elas associadas são discutidas

Dermatophytosis caused by Trichophyton raubitschekii. Report of the first case in São Paulo, Brazil

The authors report the first case of dermatophytosis caused by Trichophyton raubitschekii in a patient from the State of São Paulo with Tinea corporis lesions localized on the buttocks. Culture on Sabouraud-agar with cycloheximide permitted the isolation and identification of the fungus, and the diagnosis was confirmed by Dr. Lynne Sigler, University of Alberta, Canada. Systemic treatment with fluconazole, 150 mg/week for 4 weeks, in combination with topical treatment with isoconazole initially yielded favorable results, with recurrence of the lesions after the medication was discontinued. This is the fifth case of this dermatophytosis published in the Brazilian medical literature
