Riehl melanosis - Riehl Melanose
Riehl Melanose (Riehl melanosis) er en form for kontakteksem som starter med kløe, erytem og pigmentering. Disse symptomene sprer seg gradvis, men blir etter hvert stasjonære når sykdommen har nådd et visst stadium. Soleksponering etter bruk av enkelte parfymer eller kremer kan være en utløsende faktor.

ReferencesRiehl melanosis er ofte kjent som pigmentert kontaktdermatitt. Det er en hudtilstand som skyldes allergier, vanligvis utløst av duft og andre stoffer som finnes i kosmetiske produkter. Selv om den klassifiseres som en type dermatitt, viser Riehl melanosis pigmenteringsendringer i huden med kun minimale tegn på irritasjon. Tilstanden forekommer hyppigere hos personer med mørkere hudtoner. Nyere forskning har undersøkt effekten av mid‑fluence Q‑switched 1064‑nm laserbehandling for å behandle den dype pigmenteringen som er forbundet med Riehl melanosis. En annen studie kombinerte flere behandlinger, inkludert low‑fluence 1064‑nm Q‑switched Nd:YAG‑laser, hydrokinonkrem og oral tranexamic acid (tranexamsyre), noe som førte til betydelig forbedring hos de fleste pasienter.
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 er en hudtilstand som skyldes kontakt med visse allergener og eksponering for sollys. Den gir rask, progressiv gråbrun pigmentering av huden, noe som kan påvirke pasientene både mentalt og fysisk. Selv om den eksakte årsaken til Riehl's melanosis fortsatt er ukjent, viser eksisterende forskning en sterk sammenheng med allergeneksponering. Til behandling har både tradisjonell medisin og laserterapi blitt prøvd, ofte i kombinasjon med blekemidler påført huden. Laserterapi, spesielt Q‑switched Nd:YAG‑laser, har vist lovende resultater for Riehl's melanosis. Kombinasjon av ulike behandlingsmetoder har gitt positive resultater.
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.
