Riehl melanosis - Melanosi Di Riehl
La Melanosi Di Riehl (Riehl melanosis) è una forma di dermatite da contatto che inizia con prurito, eritema e pigmentazione; questi sintomi si diffondono gradualmente e, una volta raggiunta una certa estensione, la condizione diventa stazionaria. L'esposizione al sole, dopo l'uso di alcuni profumi o creme, può scatenare la malattia.

ReferencesRiehl melanosis è spesso conosciuta come dermatite pigmentata da contatto. Si tratta di una condizione cutanea causata da allergie, solitamente innescate da fragranze e altre sostanze presenti nei prodotti cosmetici. Sebbene sia classificata come un tipo di dermatite, Riehl melanosis presenta alterazioni della pigmentazione della pelle, con solo lievi segni di irritazione. È più comune nelle persone con tonalità della pelle più scure. Ricerche recenti hanno valutato l'efficacia del trattamento con laser mid‑fluence QSNY 1064‑nm per affrontare la pigmentazione profonda associata a Riehl melanosis. Un altro studio ha combinato diverse terapie, tra cui laser low‑fluence 1064‑nm Q‑switched Nd: YAG, crema all'idrochinone e acido tranexamicolo orale, ottenendo un miglioramento significativo nella maggior parte dei pazienti.
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 è una condizione cutanea causata dal contatto con specifici allergeni e dall'esposizione alla luce solare. Provoca una pigmentazione grigio‑marrone, rapida e progressiva, che può influire notevolmente sul benessere mentale e fisico del paziente. Sebbene la causa esatta di Riehl's melanosis sia ancora sconosciuta, gli studi indicano un forte legame con l'esposizione agli allergeni. Per il trattamento sono stati sperimentati sia farmaci tradizionali sia terapie laser, spesso in combinazione con agenti sbiancanti topici. In particolare, la terapia laser con laser Q‑switched Nd:YAG ha mostrato risultati promettenti. L'uso combinato di diversi approcci terapeutici ha prodotto esiti positivi.
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.
