Polymorphous Solar Eruption and its Association with Systemic Lupus Erythematosus

Polymorphic Light Eruption (PLE) is a dermatosis related to ultraviolet radiation (UV), which is why it occurs mainly in anatomical sites exposed to the sun. It can vary in morphology from one subject to another, however, in the same patient it is usually monomorphic and the most common form of presentation is the papular variant.
