Polymorphic light eruption
Polymorphic light eruption (PLE) is the most common of the so-called idiopathic photodermatoses, affecting 15% of healthy people in the UK, with a female to male prevalence ratio of around 2–3:1. It is typically characterised by the intermittent occurrence of transient, non-scarring, pruritic papules and vesicles, which develop hours, or sometimes days, after sun exposure and resolve over a period of between several days and a week or so. Most cases are mild, responding to caution during sun exposure, and such patients rarely present to dermatologists. However, those with moderate-to-severe disease may experience considerable discomfort and restriction of their lifestyles. This article examines the available treatment options for PLE.
