Pityriasis alba é unha afección da pel común e inofensiva que afecta principalmente a nenos e adolescentes. Moitas veces é visto como unha parte menor da dermatite atópica e está relacionado con alerxias na maioría das persoas. Pityriasis alba aparece como manchas de cor clara na pel, xeralmente en círculos ou óvalos, ás veces con un pouco de escamas e comezón. Estes parches adoitan atoparse na cara, especialmente nas meixelas, así como nos brazos e na parte superior do corpo, e son máis visibles nas persoas con tons de pel máis escuros. Ao principio, os parches poden ser un pouco vermellos pero despois desaparecen a unha cor máis clara co paso do tempo. A exposición ao sol pode facelos máis evidentes, o que pode preocupar aos pacientes ou aos pais, pero pityriasis alba adoita desaparecer por si só, restaurando a cor normal da pel. Pode levar desde uns meses a uns anos para que isto ocorra, aínda que a maioría dos casos aclaran nun ano. O tratamento xeralmente implica o uso de cremas e loções suaves, xunto con tranquilizar aos pacientes ou pais de que non é nada grave.
Pityriasis alba is a prevalent and benign dermatological condition predominantly affecting children and adolescents. The name pityriasis alba derives from its appearance, where pityriasis denotes the fine scales and alba signifies the pale color (hyperpigmentation). This skin disorder is often considered a minor manifestation of atopic dermatitis and is typically associated with a history of atopy in most individuals. Pityriasis alba is characterized by ill-defined macules and patches (or thin plaques), generally circular or oval, often with mild scaling and occasional pruritus (Macules or Patches Observed in Pityriasis Alba). The lesions are usually found on the face, especially the cheeks, arms, and upper trunk, and are more prominent in individuals with darker skin types. Initially, the lesions may exhibit mild erythema and gradually transition to a hypopigmented state over time. Sun exposure can accentuate the appearance of these lesions, which may often raise concerns regarding their cosmetic impact on patients or parents of children. However, pityriasis alba follows a spontaneous, self-resolving course, gradually restoring normal skin pigmentation. The resolution period for pityriasis alba varies from several months to a few years, although most cases typically resolve within 1 year. Treatment for this condition involves reassurance, low-potency topical corticosteroids, and mild emollients as the mainstay.
