Riehl melanosis
Riehl melanosis este o formă de dermatită de contact, care începe cu prurit, eritem și pigmentare care se răspândește treptat care, după ce atinge o anumită măsură, devine staționară. Expunerea la soare după folosirea unor parfumuri sau creme poate cauza boala.

Riehl melanosis este adesea cunoscut sub numele de dermatită de contact pigmentată. Este un tip de afecțiune a pielii cauzată de alergii, de obicei declanșată de parfum și alte substanțe găsite în produsele cosmetice. În ciuda faptului că este clasificat ca un tip de dermatită, Riehl melanosis prezintă modificări ale pigmentării pielii, cu doar semne minore de iritare. Este mai frecventă la persoanele cu tonuri de piele mai închise. Cercetări recente au explorat eficacitatea tratamentului cu laser mid-fluence QSNY 1064-nm pentru abordarea pigmentării profunde asociate cu Riehl melanosis. Un alt studiu a combinat diferite terapii, inclusiv low-fluence 1064-nm Q-switched Nd: YAG laser, cremă cu hidrochinonă și acid tranexamic oral, rezultând o îmbunătățire semnificativă pentru majoritatea pacienților.
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 este un tip de afecțiune a pielii cauzată de contactul cu anumiți alergeni și de expunerea la lumina soarelui. Conduce la pigmentarea rapidă, progresivă cenușiu-maronie a pielii, care poate afecta foarte mult pacienții atât psihic, cât și fizic. Deși cauza exactă a Riehl's melanosis este încă necunoscută, cercetările existente indică o legătură puternică cu expunerea la alergeni. Pentru tratament, s-au încercat atât medicamentele tradiționale, cât și terapia cu laser, adesea alături de utilizarea agenților de albire aplicați pe piele. Terapia cu laser, în special folosind laserul Q-switched Nd:YAG , a arătat rezultate promițătoare pentru tratarea Riehl's melanosis. Combinarea diferitelor abordări de tratament a dus la rezultate pozitive.
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.
