However, a latency of 1 to 3 weeks after sun exposure and a long healing time is typical for LE. A dermatological maxim states that “a patient gets PMLE on holiday but brings LE home.” Although PMLE is the most important differential diagnosis for cutaneous LE, it virtually never changes into LE, even if nonspecific positive antinuclear antibodies are present (2, 6).

How to prevent PMLE?

Total body radiation using UV-A and/or UV-B is suitable. Preventative radiation should only be administered under specialist medical supervision and not in a solarium in order to ensure minimal UV exposure. Topical application of broad-spectrum sunscreen is useful. This predominantly benefits UV-B-induced polymorphous light eruption. With an extremely low UV-A threshold, PMLE episodes cannot be prevented even with very potent UV-A filters. General sun protection measures such as covering with clothes and appropriate, sensible behavior are also useful. An interesting new approach to preventative external therapy involves topical application of suitable antioxidants, because pathophysiologically the inflammation reactions are most likely mediated by free radicals generated in the skin.
