Riehl melanosis - 里尔黑变病
里尔黑变病 (Riehl melanosis) 是接触性皮炎的一种形式，最初表现为瘙痒、红斑和色素沉着，逐渐扩散，达到一定程度后变得静止。使用某些香水或面霜后的阳光照射可能是导致该病的原因。

Riehl melanosis 通常称为色素接触性皮炎。这是一种由过敏引起的皮肤病，通常由化妆品中的香料和其他物质引发。尽管被归类为皮炎的一种， Riehl melanosis 仍显示皮肤色素沉着变化，只有轻微的刺激迹象。在肤色较深的人中更常见。最近的研究探讨了 mid-fluence QSNY 1064-nm 激光治疗对于解决与 Riehl melanosis 相关的深层色素沉着的有效性。另一项研究结合了不同的疗法，包括 low-fluence 1064-nm Q-switched Nd: YAG 激光、氢醌乳膏和口服氨甲环酸，大多数患者的病情得到了显着改善。
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 是一种因接触某些过敏原和暴露在阳光下而引起的皮肤病。它会导致皮肤快速、渐进地出现灰棕色色素沉着，这会对患者的精神和身体产生极大的影响。虽然 Riehl's melanosis 的确切原因仍不清楚，但现有研究表明与过敏原暴露密切相关。对于治疗，人们尝试了传统药物和激光疗法，通常同时使用应用于皮肤的漂白剂。激光疗法，特别是使用 Q-switched Nd:YAG 激光，已显示出治疗 Riehl's melanosis 的有希望的结果。结合不同的治疗方法已经取得了积极的成果。
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.
