Nummular eczema - 钱币状湿疹https://en.wikipedia.org/wiki/Nummular_dermatitis
钱币状湿疹 (Nummular eczema) 的特征是慢性或复发性发痒的硬币大小红斑块,可出现在躯干、四肢、面部和手部。镍、钴、铬酸盐和香料是钱币状湿疹 (nummular eczema) 的常见诱因。

治疗 - 非处方药
用肥皂清洗病变部位根本没有帮助,反而会使情况更糟。

治疗湿疹通常需要一周或更久的时间。
#Hydrocortisone ointment

非处方抗组胺药。西替利嗪或左西替利嗪比非索非那定更有效,但会使您昏昏欲睡。
#Cetirizine [Zytec]
#LevoCetirizine [Xyzal]

Nummular dermatitis 是一种以发痒、硬币状斑块为特征的皮肤状况。它可能与其他皮肤问题并存,例如特应性皮炎或干性皮肤湿疹。值得庆幸的是,它通常对治疗反应良好。使用含有皮质类固醇的乳膏通常可以缓解症状,许多患者最终会好转。Nummular dermatitis 也可能称为钱币状湿疹、盘状湿疹或微生物性湿疹。
Nummular dermatitis is a pruritic eczematous dermatosis characterized by multiple coin-shaped lesions. It may occur as a feature of atopic dermatitis, asteatotic eczema, or stasis dermatitis. The prognosis of this condition is excellent. Most cases can be treated successfully with conservative measures and topical corticosteroids, and a majority of patients will eventually achieve remission. Nummular dermatitis may also be referred to as nummular eczema, discoid eczema, and microbial eczema.
