    Adv Exp Med Biol 2017 ;996:111-122
    Department of Dermatology and Venereology, All India Institute of Medical Sciences, Ansari Nagar, New Delhi, 110029, India.
    Skin colour (specifically in relation to its melanin content and composition) has a marked influence on its interaction with ultraviolet light. Eumelanin has mainly photoprotective properties while pheomelanin has the ability to cause formation of reactive oxygen species. This difference is responsible for the difference in incidence and presentation of various idiopathic photodermatoses in dark skinned patients compared to those with lighter skin types. Read More

    Polymorphous Light Eruption.
    Adv Exp Med Biol 2017 ;996:61-70
    University of Genoa, Genoa, Italy.
    Polymorphous light eruption (PLE) is the commonest immuno-mediated photodermatosis. It occurs after solar or artificial UV-light exposure and affects only the sun-exposed areas with preference of the V-area of the chest, of arms and forearms, legs, upper part of the back, and rarely the face. The lesions are itching or burning, and vary morphologically from erythema to papules, vesico-papules and occasionally blisters, plaques, sometimes erythema multiforme-like, insect bite-like wheals and purpura.

    Narrowband UVB-induced iatrogenic polymorphous light eruption: a case and suggestions to overcome this rare complication.
    Dermatol Online J 2016 Jun 15;22(6). Epub 2016 Jun 15.
    UCSF Psoriasis and Skin Treatment Center.
    Polymorphous light eruption (PMLE) is the most common photodermatosis characterized by pruritic papules and papulovesicles, which appear hours to days following ultraviolet (UV) exposure. Herein, the authors report successful treatment of generalized plaque psoriasis with Goeckerman regimen in a patient despite new onset iatrogenic PMLE following narrowband (NB) UVB therapy. Although further studies are necessary, this case suggests that the co-existence of psoriasis and PMLE should not prevent the use of phototherapy; phototherapy, especially as part of the Goeckerman regimen, remains a valuable treatment option for psoriasis in patients with PMLE.

    Unilateral unique Lupus tumidus: pathogenetic mystery and diagnostic problem.
    Wien Med Wochenschr 2016 May 13;166(7-8):250-3. Epub 2016 Jan 13.
    Policlinic for Dermatology and Venereology, University Hospital Lozenetz, Koziak street 1, 1407, Sofia, Bulgaria.
    Lupus tumidus is a rare immunological disorder whose pathogenesis is not fully understood. Although on the one hand there are some differences in (1) the clinical morphology of lesions, (2) the histopathology picture, as well as in (3) serological profile of lupus tumidus patients at the current moment, the disease is regarded as a subform of chronic cutaneous lupus erythematosus. Differential diagnosis requires the exclusion of many diseases such as Jessner Kanoff lymphocytic infiltration, polymorphous light eruption, and reticular erythematous mucinosis. Read More

    Minireview: Peptide analogs and short sequence oligopeptides as modulators of skin pigmentation.
    Curr Top Med Chem 2014 ;14(12):1418-24
    Escape Therapeutics, Inc., 5941 Optical Court, San Jose, CA 95138, USA.
    Short sequence amino acids or oligopeptides have recently garnered attention for use as treatments for a myriad of dermatologic disorders due to their ability to effect and modulate various biological processes in the epidermis and dermis, rendering them promising candidates as medical and cosmeceutical therapeutics. Major advantages include their relative ease of synthesis and multitude of modifications that can be applied to enhance potency, affinity, specificity, hydrophilicity or hydrophobicity and cytotoxicity. Given the photoprotective effects of eumelanin on skin, there has been substantial interest in developing agents, particularly α-MSH analogs, that can induce 'sunless tanning' helping reduce risk of melanoma and non-melanoma skin cancer.

    Photoaggravated disorders.
    Dermatol Clin 2014 Jul;32(3):385-98, ix
    Dermatology Department, Beaumont Hospital, Beaumont Road, Beaumont, Dublin 9, Ireland; National Photodermatology Unit, Dermatology Department, Mater Misericordiae University Hospital, Eccles Street, Dublin 7, Ireland.
    Photoaggravated skin disorders are diseases that occur without UV radiation but are sometimes or frequently exacerbated by UV radiation. In conditions, such as lupus erythematosus, photoaggravation occurs in a majority of patients, whereas in conditions, such as psoriasis and atopic dermatitis, only a subset of patients demonstrate photoaggravation. Polymorphous light eruption is a common photodermatosis in all skin types, making it important to differentiate photoaggravation of an underlying disorder, such as lupus erythematosus, from superimposed polymorphous light eruption.

    Polymorphous light eruption: clinic aspects and pathogenesis.
    Dermatol Clin 2014 Jul;32(3):315-34, viii
    Research Unit for Photodermatology, Department of Dermatology, Medical University of Graz, Auenbruggerplatz 8, Graz A-8036, Austria. Electronic address:
    Polymorphous light eruption is an immunologically mediated photodermatosis with high prevalence, particularly among young women in temperate climates, characterized by pruritic skin lesions of variable morphology, occurring in spring or early summer on sun-exposed body sites. A resistance to ultraviolet radiation (UVR)-induced immunosuppression and a subsequent delayed-type hypersensitivity response to a photoantigen have been suggested as key factors in the disease. Molecular and immunologic disturbances associated with disease pathogenesis include a failure of skin infiltration by neutrophils and other regulatory immune cells on UVR exposure linked to a disturbed cytokine microenvironment.

    Photoimmunology.
    Dermatol Clin 2014 Jul 5;32(3):277-90, vii. Epub 2014 May 5.
    Department of Dermatology, UAB Skin Diseases Research Center, UAB Comprehensive Cancer Center, Birmingham VA Medical Center, University of Alabama at Birmingham, EFH 414, 1720 2nd Avenue South, Birmingham, AL 35294-0009, USA.
    The discipline that investigates the biologic effects of ultraviolet radiation on the immune system is called photoimmunology. Photoimmunology evolved from an interest in understanding the role of the immune system in skin cancer development and why immunosuppressed organ transplant recipients are at a greatly increased risk for cutaneous neoplasms. In addition to contributing to an understanding of the pathogenesis of nonmelanoma skin cancer, the knowledge acquired about the immunologic effects of ultraviolet radiation exposure has provided an understanding of its role in the pathogenesis of other photodermatologic diseases.
