ReferencesPityriasis alba je uobičajeno i bezopasno stanje kože koje uglavnom pogađa djecu i tinejdžere. Često se smatra blagim oblikom atopijskog dermatitisa i kod većine ljudi je povezan s alergijama. Pityriasis alba pojavljuje se kao svijetle mrlje na koži, najčešće u obliku krugova ili ovalnih plošica, ponekad uz blago ljuskanje i svrbež. Te mrlje najčešće se nalaze na licu, osobito na obrazima, te na rukama i gornjem dijelu tijela, a vidljivije su kod osoba tamnije kože. U početku mrlje mogu biti blago crvene, ali s vremenom izblijede u svjetliju boju. Izlaganje suncu može ih učiniti izraženijima, što može zabrinuti pacijente ili roditelje, ali pityriasis alba obično nestane sam od sebe, vraćajući normalnu boju kože. To može potrajati od nekoliko mjeseci do nekoliko godina, iako većina slučajeva nestane u roku od godinu dana. Liječenje obično uključuje korištenje blagih krema i losiona, uz uvjeravanje pacijenata i roditelja da nije ništa ozbiljno.
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.

Lečenje nije nužno; lezija se s vremenom povlači. Steroidne kreme mogu se koristiti kratko, najviše jedan do dva tjedna.
