Childhood pityriasis alba usually lasts for a few days or months and resolves spontaneously, but is prone to flare-ups. Childhood pityriasis alba is a scaly, hypopigmented skin disorder that develops on the face. It resolves on its own and usually requires no treatment. Typical lesions are white or reddish patches, either alone or in clusters, with a small amount of furfuraceous scales. It usually lasts for a few days or months and resolves spontaneously, with pale hypopigmented patches remaining after the lesions have cleared. There are no self-conscious symptoms. White furfur mostly occurs in exposed areas that are easily rubbed and exposed to sunlight, especially on the face, such as between the eyebrows, the inner part of the eyebrows, the root of the nose and the inner part of the cheeks, in front of the ears and the upper part of the ears, the hairline of the forehead, and the red part of the lips, etc. Therefore, attention should be paid to sun protection for children in the day-to-day life. If children suffer from white chaff rash, parents are advised to bring them to the hospital in time for treatment under the guidance of doctors.
