Photocontact Dermatitis and Its Clinical Mimics: an Overview for the Allergist.

Clin Rev Allergy Immunol 2019 Feb;56(1):32-40

Department of Dermatology, The University of Texas Southwestern, 5323 Harry Hines Blvd, Dallas, TX, 75390-9069, USA.

Photo-contact dermatitis (PCD) describes the adverse cutaneous reaction that occurs in some patients as a result of simultaneous exposure to a contactant and to light. PCD can be subdivided into photo-allergic and photo-irritant dermatitis depending on whether the contactant respectively invokes an allergic or irritant reaction. Photo-irritant reactions are commonly caused by plants, psoralens, and medications taken internally, whereas photo-allergic reactions are commonly caused by sunscreens and topical nonsteroidal anti-inflammatory medications.

Expression of E-cadherin, syndecan 1, Ki-67, and maintenance minichromosome 3 in tissue lesions of actinic prurigo obtained by incisional biopsy.

Indian J Pathol Microbiol 2018 Apr-Jun;61(2):225-227

Department of Stomatology, Institute of Biomedical Sciences, Autonomous University of Ciudad Juarez, Chihuahua, Mexico.

Actinic prurigo (AP) is an idiopathic photodermatosis; the initial manifestations usually occur during the first decades of life but can appear at any age. Cases are usually diagnosed late once the lesions have exacerbated; due to the extensive involvement of the vermilion border and the etiology, it has been confused with and related to a potentially malignant process. Syndecan-1 and E-cadherin were positive in the epidermis, with moderate-to-intense staining in 100% of samples. Read More

Polymorphic light eruption and IL-1 family members: any difference with allergic contact dermatitis?

Photochem Photobiol Sci 2017 Sep;16(9):1471-1479

Department of Medicine, Surgery and Dentistry, "Scuola Medica Salernitana" University of Salerno, Italy.

Polymorphic light eruption (PLE) is described as a delayed-type hypersensitivity reaction (DTHR) toward a de novo light-induced antigen, yet to be identified. In effect, the inflammatory pathways of PLE and allergic contact dermatitis (ACD) share common patterns in terms of the mediators involved from the innate and adaptive immune system participating in the DTHR. As we have previously highlighted the role of interleukin (IL)-1 family members in ACD, we hypothesised that the same mediators could have similar functions in PLE. Read More

Efficacy of a Daily Protective Moisturizer with High UVB and UVA Photoprotection in Decreasing Ultraviolet Damage: Evaluation by Reflectance Confocal Microscopy.

Acta Derm Venereol 2017 Nov;97(10):1196-1201

Melanoma Unit, Dermatology Department, Hospital Clínic and IDIBAPS (Institut d'Investigacions Biomèdiques August Pi i Sunyer), Barcelona, Spain.

Patients with photodermatoses or actinic keratosis benefit from very high ultraviolet B-ultraviolet A (UVB-UVA) photoprotection. However, poor compliance is an issue that jeopardizes adequate protection, leading to disease recurrence. This study evaluated the efficacy of a daily protective moisturizer with high UVB and UVA photoprotection applied 8 h before irradiation. Read More

Successful Short Desensitization Treatment Protocol with Narrowband UVB Phototherapy (TL-01) in Polymorphic Light Eruption.

Actas Dermosifiliogr 2017 Oct 23;108(8):752-757. Epub 2017 May 23.

Dermatology Department, Hospital Clínic de Barcelona, Barcelona, Spain.

Introduction: Polymorphic light eruption (PLE) is a common idiopathic photodermatosis that typically presents with pruritic papular or papulovesicular lesions on sun-exposed skin between spring and autumn. In many subjects PLE is mild, and can usually be prevented by the use of broad-spectrum topical sunscreens and a gradual increase in sunlight exposure. However, in some individuals, sunlight exposure results in florid PLE and they often benefit from prophylactic desensitization treatment using phototherapy in early spring, an artificial method that induces a "hardening" phenomenon.

Photodermatoses: Kids are not just little people.

Clin Dermatol 2016 Nov - Dec;34(6):724-735. Epub 2016 Jul 12.

University of Connecticut School of Medicine, Department of Dermatology, Farmington, CT.

Photodermatoses are a group of skin disorders caused by abnormal reaction to ultraviolet radiation. Photodermatoses are divided into four groups: (1) immunologically mediated photodermatoses; (2) chemical- and drug-induced photodermatoses; (3) photoaggravated dermatoses; and (4) hereditary photodermatoses. This contribution discusses differences in the approach and diagnosis of pediatric and adult patients with suspected photodermatoses, focusing on immunologically mediated photodermatoses and chemical- and drug-induced photodermatoses.

Microbial elements as the initial triggers in the pathogenesis of polymorphic light eruption?

Exp Dermatol 2016 12;25(12):999-1001

Research Unit for Photodermatology, Department of Dermatology, Medical University of Graz, Graz, Austria.

The primary trigger of polymorphic light eruption (PLE) remains to be uncovered. We hypothesize that PLE may be initiated by elements resulting from UV-induced damage to microbial communities of the skin, leading to a cascade of events eventually resulting in the skin rash of the disease. One mechanism by which epidermal injury by UV radiation could trigger PLE are danger signals such as damage or pathogen associated molecular patterns DAMP/PAMPs or commensal-associated molecular patterns (CAMPs).

Photohardening of polymorphic light eruption patients decreases baseline epidermal Langerhans cell density while increasing mast cell numbers in the papillary dermis.

Exp Dermatol 2014 Jun;23(6):428-30

Research Unit for Photodermatology, Department of Dermatology, Medical University of Graz, Graz, Austria.

The pathogenesis of polymorphic light eruption (PLE) has been linked to a lack of UV-induced immune suppression. To determine the role of Langerhans cells (LC), mast cells and regulatory T cells, biopsies from PLE patients were taken from exposed sites in spring before and after photohardening with 311 nm or PUVA as well as again in summer. Skin sections were assessed for the presence of Langerin/CD1a+ LC and CD3+, CD4+, CD25+ or FoxP3+ T cells and mast cells. Read More

Thalidomide is a synthetic glutamic acid derivative first introduced in 1956 in Germany as an over the counter medications. It was thought to be one of the safest sedatives ever produced as it was effective in small doses, was not addictive, and did not have acute side-effects such as motor impairment, but was quickly removed from market after it was linked to cases of severe birth defects. The Food and Drug Administration approved use in the treatment of erythema nodosum leprosum. Read More

Photochem Photobiol Sci 2013 Jan;12(1):65-77

Department of Dermatology and Venereology, All India Institute of Medical Sciences, Ansari Nagar, New Delhi-110029, India.

Photodermatoses are a group of skin diseases primarily caused by, or exacerbated by exposure to ultraviolet and or visible radiation. The effect of sunlight on skin depends on a number of factors including skin colour, skin phototype and the content and type of melanin in the skin. There are only a few studies describing photodermatoses in populations with dark skin. Read More

Current knowledge in inflammatory dermatopathology.

Dermatol Clin 2012 Oct 28;30(4):667-84, vii. Epub 2012 Jul 28.

UC Davis Dermatopathology Service, Department of Dermatology, University of California Davis School of Medicine, 3301 C Street, Suite 1400, Sacramento, CA 95816, USA.

The complex and fascinating spectrum of inflammatory skin disease, and the comprehension of it, is ever expanding and evolving. During the first decade of the 21st century, numerous advances in the understanding of inflammatory disease mechanisms have occurred, particularly in psoriasis and atopic dermatitis. Continuation of this trend will assure a future in which molecular tests for biomarkers of immediate clinical relevance are used in routine patient care, not only for diagnosis but also for prognosis and management.

Case for diagnosis. Actinic prurigo.

An Bras Dermatol 2010 Sep-Oct;85(5):733-5

Pontifícia Universidade Católica de Campinas, SP, Brasil.

A 13-year-old black boy had pruritic papular and nodular lesions on his forearms associated to edema of the lower lip, photophobia, conjunctivitis and pterygium. Skin biopsy of the lower lip revealed acanthosis, spongiosis with dermal perivascular mononuclear cell infiltration composed by lymphocytes, plasma cells and eosinophils consistent with actinic prurigo. Lesions improved considerably with the use of thalidomide 100mg/ day. Read More

Innovative uses of thalidomide.

Dermatol Clin 2010 Jul;28(3):577-86

Department of Dermatology, Baylor College of Medicine, BCM Debakey Building M220, One Baylor Plaza, Mail Stop BCM368, Houston, TX 77030, USA.

Thalidomide is approved for treating erythema nodosum leprosum and multiple myeloma, but it has also emerged as a useful treatment option for many refractory dermatologic disorders. Some of the innovative but off-label uses of thalidomide include aphthous stomatitis, Behçet's disease, lupus erythematosus, prurigo nodularis, sarcoidosis, actinic prurigo, graft-versus-host disease, Langerhans cell histiocytosis, erythema multiforme, lichen planus, Kaposi sarcoma, Jessner lymphocytic infiltrate, uremic pruritus, pyoderma gangrenosum, scleroderma, scleromyxedema, and necrobiosis lipoidica. This article reviews the background, pharmacology, and innovative uses of thalidomide in dermatology. Read More

Chronic actinic prurigo presenting in an adopted child.

Pediatr Dermatol 2010 Jan-Feb;27(1):97-8

Loma Linda University School of Medicine, Loma Linda University, Loma Linda, California, USA.

In diagnosing actinic prurigo (AP), the patients' ethnic background is very helpful as this condition is associated with very specific ethnic groups. We discuss a patient with an unknown family history who presented with a rash that initially seemed like lupus, but was subsequently diagnosed as AP upon further evaluations. Read More

Immunologically mediated photodermatoses: diagnosis and treatment.

Am J Clin Dermatol 2009 ;10(3):169-80

Department of Dermatology, Ruhr-University Bochum, Bochum, Germany.

Electromagnetic radiation may cause distinct skin conditions. The immunologically mediated photodermatoses (IMP, previous term: idiopathic photodermatoses) represent a heterogenous group of disorders presenting with pathologic skin reactions caused by optical radiation, particularly in the UVA wavelength region. The exact pathomechanism in IMP remains to be elucidated; however, it is very likely (auto)-immunologic in nature. Read More
