Riehl melanosis - Riehl黑变病https://en.wikipedia.org/wiki/Riehl_melanosis
Riehl黑变病 (Riehl melanosis) 是接觸性皮膚炎的一種形式,最初表現為瘙癢、紅斑和色素沉著,逐漸擴散,達到一定程度後變得靜止。使用某些香水或乳霜後的陽光照射可能是導致疾病的原因。

      Riehl melanosis 通常稱為色素接觸性皮膚炎。這是一種由過敏引起的皮膚病,通常由化妝品中的香料和其他物質引發。儘管被歸類為皮膚炎的一種, Riehl melanosis 仍顯示皮膚色素沉著變化,只有輕微的刺激跡象。在膚色較深的人中較常見。最近的研究探討了 mid-fluence QSNY 1064-nm 雷射治療對於解決與 Riehl melanosis 相關的深層色素沉著的有效性。另一項研究結合了不同的療法,包括 low-fluence 1064-nm Q-switched Nd: YAG 雷射、氫醌乳膏和口服氨甲環酸,大多數患者的病情得到了顯著改善。
      Riehl melanosis (RM), commonly called pigmented contact dermatitis, is considered an acquired form of allergic contact dermatitis, typically to fragrance and other ingredients of cosmetic products. Although it is considered as a dermatitis, it presents clinically with hyperpigmentation over the face and shows pigment incontinence with minimal eczematous changes on histology. The condition is more commonly seen in dark-skinned people, causing an important psychosocial impact. A recent study showing the higher effectiveness of mid-fluence QSNY 1064-nm laser in targetting the deep pigmentation of RM has also been conducted. Another study used a combination of therapies to include low-fluence, 1064-nm, Q-switched Nd: YAG laser, hydroquinone cream, and oral tranexamic acid, with the majority of patients experiencing significant improvement.

      Riehl's melanosis 是一種因接觸某些過敏原和暴露在陽光下而引起的皮膚病。它會導致皮膚快速、漸進地出現灰棕色色素沉著,這會對患者的精神和身體產生極大的影響。雖然 Riehl's melanosis 的確切原因仍不清楚,但現有研究表明與過敏原暴露密切相關。對於治療,人們嘗試了傳統藥物和雷射療法,通常同時使用塗抹在皮膚上的漂白劑。雷射療法,特別是使用 Q-switched Nd:YAG 激光,已顯示出治療 Riehl's melanosis 的有希望的結果。結合不同的治療方法已經取得了積極的成果。
      Riehl's melanosis (RM) is a contact photodermatitis, with fast progressive gray-brown skin pigmentation as the main manifestation, which can seriously affect the psychology and physiology of patients. Currently, although the etiological factors of Riehl's melanosis is still be unknown, the existing literature proves clearly the cause of it is related to the contacting with suspected allergens. For decades, there has been no standard method for the treatment of RM, but with both conventional drug therapy and laser therapy having been attempted. Topical application of bleaching agents is mainly used as an auxiliary treatment modality. The laser treatment modality remains a hot spot, among which Q-switched Nd:YAG laser is well received for RM. Positive outcomes have been achieved by the combined treatment modalities attempted in recent years also achieve positive outcomes.
