Introdução: A pitíríase liquenóide (PL) é uma dermatose
pouco comum e apresenta duas variantes major: a pitiríase liquenóide
e varioliforme aguda (PLEVA) e a pitiríase líquenóide
crónica (PLC). A sua classificação baseia-se essencialmente nas
características clínicas e histológicas.
Caso Clínico: Uma criança do sexo masculino, com seis
anos de idade, foi referenciada à Consulta de Dermatologia
Pediátrica com história de uma erupção cutânea generalizada
recorrente, com seis meses de evolução, compatível com o diagnóstico
de PLC, corroborado pelo resultado histológico.
Discussão: Na PLC, as lesões cutâneas típicas são geralmente
assintomáticas e consistem em pápulas eritematosas,
com descamação micácea central, facilmente destacável, revelando
uma superfície brilhante (liquenóide). Geralmente, tem
uma resolução espontânea, após um longo período de remissões
e recorrências. As opções terapêuticas incluem a corticoterapia
tópica ou sistémica, eritromicina oral, helioterapia, entre
outras.
ABSTRACT Introduction: Pityriasis lichenoides (PL) is an uncommon skin disorder with two major variants: pityriasis lichenoides et varioliformis acuta (PLEVA) and pityriasis lichenoides chronica (PLC). Its classification is essentially based on clinical and histological features. Case report: A six-year-old boy was referred to the Pediatric Dermatology Consultation with history of a recurrent generalized skin eruption since the last 6 months, favoring the diagnosis of PLC that was supported by the histological findings. Discussion: In general, the typical cutaneous lesions of PLC are asymptomatic and consist of erythematous papules with a central micaceous scale that can easily be detached to reveal a shiny surface (lichenoid). It usually resolves spontaneously following a long period of remissions and recurrences. The treatment options include topical and oral corticosteroids, oral erythromycin and heliotherapy, among others.
