Pityriasis albahttps://en.wikipedia.org/wiki/Pityriasis_alba
Pityriasis alba is a skin condition, a type of dermatitis, commonly seen in children and young adults as dry, fine-scaled, pale patches on the face. Lesions are round or oval raised or flat, of 0.5–2 cm in size although may be larger if they occur on the body (up to 4 cm). The number of the lesion is usually 4~5. The affected areas are dry with very fine scales. They most commonly occur on the cheeks.

No treatment is required, and the lesion subsides over time. Steroid creams may be tried for short periods of one to two weeks.

      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.
