Dermamelan ® Treatment for Melasma and Hyperpigmentation Dermamelan ® treatment for melasma and hyperpigmentation Jean Luc Levy Expert Laser, Dermatologist Lausanne, Switzerland [email protected] Incidence of Melasma Caucasian Melasma is estimated to occur in 50%-70% of pregnancies among US women, usually during the 2nd or 3rd trimester of pregnancy. Asian In Asian countries, the estimated prevalence of melasma within skin type III-V is estimated to be as high as 40% in females and 20% in males. Hispanic Among Mexican women, the incidence is estimated to be about 80%, with more than one-third of these patients having the disease for life.

  • Laser Treatment for Pigmentation
    Laser treatment for pigmentation Sunspots and freckles In lesions such as solar lentigines (sun induced age spots), lentigo simplex and ephelides (freckles) the pigment (melanin) is in the top layers of the skin. Many lasers that selectively target melanin or simply remove the top layers will lead to improvement. One to two treatments will be necessary. There are many non-laser treatment approaches to treat such spots. However, if laser therapy is chosen, there are many different types of laser that can be used including Q-switched lasers [Q switched (QS) alexandrite, QS ruby (694nm)], long-pulsed, fractionated thulium (1927nm) and ablative lasers. IPL (filter 500-600nm) can also be very effective. However, it is common to see the pigmentation return over time. Treatments need to be avoided if the skin is tanned because this greatly increases the risk of complications. Seborrhoeic warts and dermatosis papulosa nigra Some conditions that present as dark spots are in fact wart-like and sit on the surface of the skin such as seborhoeic keratoses and dermatosis papulosa nigra and epidermal naevi. These conditions require physical removal. This is most commonly treated with a curette if thick or with fine wire diathermy particularly for the dermatosis papulosa nigra. Ablative lasers may also be used including CO2 in combination with a curette or an erbium YAG laser which reliably gives the best results. These lesions have a tendency to return over a number of years and maintenance treatments may be needed. Pigmented birth marks – Becker’s naevus Current lasers are unable to remove pigmented birthmarks without scarring.

Solar lentigo, ephelides, café au lait spots, and other melanoses represent a cosmetic issue for a growing number of subjects. The Q-switched 1064/532-nanometer (nm) laser may be considered the gold standard for manage- ment of these aesthetic issues. A new generation of Q-switched lasers, capable of concentrating the energy pulse in the spectrum of hundreds of picoseconds, is emerging, promising better results than previous ones. In this paper, we report the use of a Q-switched laser with a picosecond pulse to Citation: Silvestri, M.; Bennardo, L.; manage hypermelanoses.

  • Lentigo Simplex= النمشة البسيطة
    اﻠﺒﺴﻴﻄﺔ اﻠﻨﻤﺸﺔ =Lentigo simplex LENTIGO SIMPLEX Epidemiology The frequency of lentigo simplex in children and adults has not been determined. There does not appear to be a racial or gender predilection. Lentigo simplex is the most common histopathologic pattern of darkly pigmented lesions excised from acral sites of darkly pigmented races. Pigmented nail bands, noted in up to 20 percent of Japanese, may have histopathologic features of lentigo simplex. For agminated lentigines, the population prevalence is unknown, but it is believed to be rare. 1 / 8 اﻠﺒﺴﻴﻄﺔ اﻠﻨﻤﺸﺔ =Lentigo simplex Etiology and Pathogenesis The increased density of melanocytes in lentigines is presumably due to an underlying developmental or intrinsic defect in melanocyte homeostasis. In some lentigines, the presence of melanin macroglobules in melanocytes and keratinocytes suggests that defects affecting melanization pathways are also involved. The presence of lentigo simplex in association with somatic abnormalities in such diverse conditions as Peutz-Jeghers syndrome, LEPOARD syndrome (lentigines; electrocardiogram conduction defects; ocular hypertelorism; pulmonary stenosis; abnormalities of genitalia; retardation of growth, and sensorineural deafness), and LAMB/myxoma syndrome suggests that lentigo development may be influenced by a number of different genetic factors. For agminated lentigines, it is possible that chromosomal mosaicism plays a role in the development of the localized collection of lentigines. Clinical Findings HISTORY Unlike solar lentigines, lentigo simplex is thought to be largely UVR independent. Lentigo simplex may appear as early as the first decade and may occur anywhere on skin or mucous membranes. Generalized lentigines may occur as an isolated phenomenon without known familial aggregation and first appear at birth, during infancy, or during adulthood.

Malaysian Family Physician. 2010;5(1):9-12 CASE HISTORY Figure 2: Dorsal view of both forearms Mr A is an 80 year old man who presents with several warty skin lesions on his forearms for past 6 months. There was no complaint of pain or itch except occasional irritation when he accidentally rubbed against them. He noticed that these skin lesions had gradually increased in size and number. Mr A is generally well and healthy with a functional age of 65 years. He does not have any medical problem except for mild hypertension controlled well with atenolol 100mg daily. He used to work as a Chinese opera singer in his younger days and is now retired. Currently he spends his time providing service in church and help to make handicrafts to raise funds for the church and charitable old folk’s homes. Figure 3: Closer dorsal view of right forearm Physical examination (Figures 1-3) reveals extensive solar damaged skin on sun exposed areas of both forearms. There are scattered areas of hyperpigmentation (solar lentigo), isolated patches of hypopigmentation (solar hypomelanosis), skin atrophy, presence of wrinkles, telangiectasia and superficial areas of ecchymosis.
