    [Melanocytoma and meningeal melanocytosis, similar but different lesions].
    Cir Cir 2017 Jan 23. Epub 2017 Jan 23.
    Servicio de Patología, Hospital Juárez de México, Ciudad de México, México.
    Background: Meningeal melanomatosis is an extra-axial well-encapsulated malignant tumour with diffuse meningeal growth and dark coloration (due to high melanin contents), while meningeal melanocytoma is the focalized benign variant. Melanocytic lesions may be secondary to melanoma or be histologically benign, however, their diffuse nature makes them impossible to cure. Melanocytosis is a diffuse tumour that can form solitary extra-axial tumours, which invades the parenchyma and presents signs of malignancy with increased mitosis and Ki67, observed in 1 to 6% of immunopathological exams.

    Mosaic NRAS Q61R mutation in a child with giant congenital melanocytic naevus, epidermal naevus syndrome and hypophosphataemic rickets.
    Clin Exp Dermatol 2017 Jan 30;42(1):75-79. Epub 2016 Nov 30.
    Department of Paediatric Dermatology, Birmingham Children's Hospital NHS Foundation Trust, Birmingham, UK.
    The association of hypophosphataemic rickets with verrucous epidermal naevus (EN) and elevated fibroblast growth factor 23 levels is known as cutaneous-skeletal hypophosphataemia syndrome (CSHS), and can be caused by somatic activating mutations in RAS genes. We report a unique patient with CSHS associated with giant congenital melanocytic naevus (CMN), neurocutaneous melanosis and EN syndrome, manifesting as facial linear sebaceous naevus, developmental delay and ocular dermoids. An activating mutation Q61R in the NRAS gene was found in affected skin and ocular tissue but not blood, implying that the disparate manifestations are due to a multilineage activating mutation (mosaic RASopathy).

    Theoretical review of the treatment of pigmented lesions in Asian skin.
    Laser Ther 2016 Oct;25(3):179-184
    Department of Plastic Surgery, Tokai University.
    Asian skin has a higher epidermal melanin content, making it more likely to develop adverse pigmentary reactions following laser surgery. The nanosecond lasers are the gold standard for the treatment of pigmented lesions, but the risk of complications, such as post-inflammatory hyperpigmentation, is increased in dark-skinned patients. Intense Pulsed Light (IPL) or long-pulsed lasers are available for treating superficial pigmented lesions, and fewer complications are seen when using these devices compared to the nanosecond lasers.

    Downregulation of melanogenesis: drug discovery and therapeutic options.
    Drug Discov Today 2017 Feb 28;22(2):282-298. Epub 2016 Sep 28.
    College of Pharmacy and Institute of Drug Research and Development, Chungnam National University, Daejeon 34134, South Korea.
    Melanin, primarily responsible in humans for hair, eye and skin pigmentation, is produced by melanocytes through a process called melanogenesis. However, the abnormal accumulation of melanin causes dermatological problems such as café-au-lait macules ephelides (freckles), solar lentigo (age spots) and melasma, as well as cancer and vitiligo. Hence the regulation of melanogenesis is very important for treating hyperpigmentary disorders. Read More
