“…Our finding suggests that the hyperpigmentation is because of increased melanin in the dermis, which possibly originates from the epidermis because of injury to the basal cells. Riehl melanosis, also known as pigmented contact dermatitis, seems to be associated with friction or contact dermatitis . In this study, the etiology of several cases of pigmentary incontinence was friction or contact dermatitis.…”

“…Riehl melanosis, also known as pigmented contact dermatitis, seems to be associated with friction or contact dermatitis. 10,11 In this study, the etiology of several cases of pigmentary incontinence was friction or contact dermatitis. We infer that pigmentary incontinence in PIH might have a similar pathophysiology as Riehl melanosis.…”

“…Clinically, melanin pigment in upper dermis is so slowly absorbed that the hyperpigmentation appears to persist or worsen over time if consistent contact of possible allergens happens (17). Riehl’s melanosis, first described by Riehl as “war melanosis” in 1917, similarly affects the face, and is related with nutritional factors and sensitizing chemicals in cosmetics (181920). Riehl’s melanosis is considered synonymous with PCD, with the common allergen being fragrances and chemicals in cosmetics (19).…”

Acquired Bilateral Dyspigmentation on Face and Neck: Clinically Appropriate Approaches

et al. 2016

Facial dyspigmentation in Asian women often poses diagnostic and therapeutic challenges. Recently, a distinctive bilateral hyperpigmentation of face and neck has occasionally been observed. This study was performed to investigate the clinico-pathological features of this dyspigmentation as well as proper treatment approaches. We retrospectively investigated the medical records including photographs, routine laboratory tests, histopathologic studies of both lesional and peri-lesional normal skin and patch test of thirty-one patients presented acquired bizarre hyperpigmentation on face and neck. The mean age of patients was 52.3 years and the mean duration of dyspigmentation was 24.2 months. In histologic evaluations of lesional skin, a significantly increased liquefactive degeneration of basal layer, pigmentary incontinence and lymphocytic infiltration were noted, whereas epidermal melanin or solar elastosis showed no statistical differences. Among 19 patients managed with a step-by-step approach, seven improved with using only topical anti-inflammatory agents and moisturizer, and 12 patients gained clinical benefit after laser therapy without clinical aggravation. Both clinical and histopathologic findings of the cases suggest a distinctive acquired hyperpigmentary disorder related with subclinical inflammation. Proper step-by-step evaluation and management of underlying subclinical inflammation would provide clinical benefit.

“…Li et al [25] published recently a work on the effi cacy and safety of an IPL device (Lumenis One; Lumenis, Santa Clara, CA, USA; 590-/640-/ 695-nm cut-off fi lters; fl uence, 11 -17 J/cm 2 , with triplepulse mode; pulse width, 3 -4 ms; delay time, 35 -40 ms) in the treatment of Riehl melanosis in a split-face study of six patients (Fitzpatrick skin type IV). In terms of histological analysis, the authors reported signifi cantly fewer melanin granules and melanophages in the treated side as compared with the control side after 10 IPL sessions.…”

“…Haddad et al [64] evaluated the effect of increasing the fl uence (20,25,40, and 50 J/cm 2 ) of an IPL device on the outcome of ALA-PDT (single treatment, 2-h incubation) in 24 patients with AK and photodamaged skin. The assessment 8 weeks after treatment indicated that AK clearance improved with increasing fl uence.…”

Intense pulsed light sources (IPLs) consist of fl ash lamps with bandpass fi lters and emit incoherent polychromatic pulsed light of a high intensity and determined wavelength spectrum, fl uence, and pulse duration. The combination of prescribed wavelengths, fl uencies, pulse durations, and pulse intervals facilitates the treatment of a wide spectrum of skin conditions. Hereby, IPLs follow the basic principle of a more or less selective thermal damage of the target. This review discusses the current literature on IPLs with regard to the treatment of unwanted hair growth, vascular lesions, pigmented lesions, and as a light source for photodynamic therapy and skin rejuvenation. It also summarizes the physics of IPLs and provides guidance for the practical use of IPLs.Keywords: laser; dermatology; vascular lesions; pigmented lesions; hair removal; skin. ZusammenfassungHochenergetische Blitzlampen, auch "intense pulsed light sources (IPLs)", ( intense pulsed light [IPL]) emittieren hochenergetisches, inkoh ä rentes Licht, welches mit Filters ä tzen auf einen gew ü nschten Wellenl ä ngenbereich eingegrenzt werden kann. Die Energiedichte, die Intensit ä t und die Pulsdauer kann in Grenzen variiert werden. Somit k ö nnen hochenergetische Blitzlampen ein vergleichsweise breites Indikationsfeld erschlie ß en. Hierbei folgt die Technologie den Prinzipien einer eingeschr ä nkt selektiven Photothermolyse der entsprechenden Zielstruktur. In diesem Review soll ein Update der Literatur zu hochenergetischen Blitzlampen geliefert werden. Schwerpunkte sind hierbei die Behandlung unerw ü nschten Haarwuchses, vaskul ä rer L ä sionen, pigmentierter L ä sionen und der Einsatz als Lichtquelle zur photodynamischen Therapie und zur Photorejuvenation.Schl ü sselw ö rter: Laser; Dermatologie; Vaskul ä re L ä sionen; Pigmentierte L ä sionen; Haut.
