定义
一种常见的病因不明的低度炎症性皮肤病,儿童面部出现多个细小的脱屑斑,肩部和上臂较少见。最初可能是轻度红斑,但很快变成色素减退,表面有细小鳞屑。组织病理学表现为轻度亚急性海绵状皮炎,黑色素减少。这在色素性皮肤儿童中更为突出,可能引起对白癜风的关注。
A common low grade inflammatory dermatosis of unknown aetiology in which multiple small finely scaling macules appear on the face, and less commonly the shoulders and upper arms, of children. These may initially be mildly erythematous but soon become hypopigmented with fine surface scale. Histopathologically there is a mild subacute spongiotic dermatitis with reduction in melanin. It is more prominent in children with pigmented skin and may give rise to concern about vitiligo.
