Pityriasis alba - 버즘 (백색 잔비늘증)
References
Pityriasis alba 는 주로 어린이와 청소년에게 영향을 미치는 흔하고 무해한 피부 상태입니다. 이는 종종 아토피성 피부염의 사소한 부분으로 간주되며 대부분의 사람들에게 알레르기와 관련이 있습니다. Pityriasis alba 는 피부에 밝은 색의 반점으로 나타나며 일반적으로 원형이나 타원형이며 때로는 약간의 각질과 가려움증이 동반됩니다. 이 반점은 얼굴, 특히 뺨, 팔, 상체에서 흔히 발견되며, 피부색이 어두운 사람에게서 더 눈에 띕니다. 처음에는 패치가 약간 빨간색일 수 있지만 시간이 지남에 따라 밝은 색상으로 희미해집니다. 햇빛에 노출되면 증상이 더욱 뚜렷해져서 환자나 부모가 걱정할 수도 있지만 pityriasis alba 는 대개 저절로 사라지고 피부의 정상적인 색이 회복됩니다. 대부분의 경우 1년 이내에 해결되지만 이러한 일이 발생하는 데는 몇 달에서 몇 년이 걸릴 수 있습니다. 치료에는 일반적으로 순한 크림과 로션을 사용하고 환자나 부모에게 심각한 것이 아니라고 안심시키는 방법이 포함됩니다.
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.
