Pityriasis alba er en almindelig og harmløs hudlidelse, der for det meste rammer børn og teenagere. Det ses ofte som en mindre del af atopisk dermatitis og er forbundet med allergi hos de fleste mennesker. Pityriasis alba viser sig som lyse pletter på huden, sædvanligvis i cirkler eller ovaler, nogle gange med en smule skæl og kløe. Disse pletter findes ofte i ansigtet, især kinderne, samt armene og overkroppen, og de er mere mærkbare hos mennesker med mørkere hudtoner. I starten kan pletterne være lidt røde, men derefter falme til en lysere farve med tiden. Soleksponering kan gøre dem mere tydelige, hvilket kan bekymre patienter eller forældre, men pityriasis alba går som regel væk af sig selv og genopretter hudens normale farve. Det kan tage alt fra et par måneder til et par år, før dette sker, selvom de fleste tilfælde klarer sig inden for et år. Behandling indebærer normalt brug af milde cremer og lotioner, sammen med at forsikre patienter eller forældre om, at det ikke er noget alvorligt.
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.
