Classification
Sunlight has been documented to trigger numerous skin conditions and the confusing terminology and categorisation previously has made the correct diagnosis and subsequent treatment difficult.Variants of PLE have been described:
Juvenile spring eruption is a cutaneous condition that affects the helices of the ears, particularly in boys, because their ears are relatively more exposed to sunlight. Benign summer light eruption is a cutaneous condition, and a name used in continental Europe, particularly France, to describe a clinically short-lived, itchy, papular eruption particularly affecting young women after several hours of sunbathing at the beginning of summer or on sunny vacations. Actinic Prurigo is a hereditary form of PLE occurring typically in Native Americans. Treatment
Management entails regulating triggers whilst simultaneously inducing "hardening"; that is, steadily increasing exposure to sunlight, as light sensitivity is reduced with repeated sun exposureCovering up with densely woven clothing has also been shown to help, in addition to applying a broad-spectrum, water-resistant semi-opaque sun protection factor (SPF) 50+ sunblock cream before sun exposure and then every two hours thereafter confers some protection.The application of topical corticosteroids may lessen the redness and itch, and for preventing predictable holiday flare-ups, short courses of oral corticosteroids are sometimes considered.Another treatment option is a supervised course of low dose phototherapy, usually undertaken in winter. If resistant, the administration of hydroxychloroquine in early spring is sometimes considered.As sun exposure is avoided, vitamin D levels may fall and hence supplements are sometimes advised.
This includes emotional distress, anxiety and depression

History
Thomas Bateman, following on from findings of his predecessor, Robert Willan, first recorded a description of PLE in the nineteenth century, defining it as eczema solare with recurrent non scarring eczematous lesions triggered by sun exposure.Danish physician Carl Rasch first described the eczema-like polymorphic light eruption in 1900, following his interest in the effect of sunlight on the skin. He has since been credited with coining the term "polymorphic light eruption". See also
