Alopecia frontal fibrosante: relato de seis casos

Abstract

Alopecia frontal fibrosante é forma progressiva de alopecia cicatricial. Os casos iniciais foram relatados a partir 1994, na Austrália, em pacientes do sexo feminino pós-menopausa. Desde então inúmeros casos foram descritos na literatura sugerindo que ela é mais prevalente do que inicialmente se supunha. Seu curso progressivo se assemelha ao da alopecia androgenética; histologicamente, entretanto, o infiltrado liquenóide é evidente. O artigo relata seis casos brasileiros e discute a alopecia frontal fibrosante dentro do grupo das alopecias cicatriciais, como variante do líquen plano pilar.

“…However, it still remains more frequent in women, with an average age of 66 years. 7,8,9 Its etiology still remains a mystery. The fact that the disease has appeared recently increases the possibility of environmental factors 10 being involved with its etiology.…”

“…The majority of the cases have been reported in European countries and North America, while a few have been described in Asian countries 11 . Only one report, out of 6 Brazilian cases 8 , was found in the medical literature.…”
