Nummular eczema - 錢幣狀濕疹https://en.wikipedia.org/wiki/Nummular_dermatitis
錢幣狀濕疹 (Nummular eczema) 的特徵是慢性或復發性發癢的硬幣大小紅斑。它可出現在軀幹、四肢、臉部與手部。鎳、鈷、鉻酸鹽和香料是錢幣狀濕疹 (Nummular eczema) 的常見誘因。

治療 - 非處方藥
用肥皂清洗病變部位根本沒有幫助,反而會使情況惡化。

治療濕疹通常需要一週或更長時間。
#Hydrocortisone ointment

非處方抗組織胺藥物。西替利嗪或左西替利嗪比非索非那定更有效,但可能會引起嗜睡。
#Cetirizine [Zytec]
#LevoCetirizine [Xyzal]

Nummular dermatitis 是一種以發癢、硬幣狀斑塊為特徵的皮膚狀況。它可能與其他皮膚問題同時出現,例如異位性皮膚炎或乾性皮膚濕疹。值得慶幸的是,該疾病通常對治療反應良好。使用含有皮質類固醇的乳膏可緩解症狀,多數患者最終會好轉。Nummular dermatitis 亦可稱為錢幣狀濕疹、盤狀濕疹或微生物性濕疹。
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.
