PITYRIASIS LICHENOIDES CHRONICA IN A CHILD
Keywords:Childhood, pityriasis lichenoides, pityriasis lichenoides et varioliformis acuta
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.
