Pitiríase rósea

Abstract

Pitiríase rósea é doença inflamatória aguda da pele, que regride espontaneamente, normalmente sem deixar seqüelas, em período que varia de quatro a oito semanas. Clinicamente é caracterizada pelo aparecimento de típicas lesões eritêmato-pápulo-escamosas. Atinge todas as idades, embora seja mais comumente observada entre 10 e 35 anos. Apesar de exaustivas pesquisas, sua etiologia ainda permanece desconhecida. São discutidos alguns aspectos epidemiológicos, anatomoclínicos, diagnósticos diferenciais, doenças associadas, com ênfase no tratamento e etiologia da doença.
