| To the Editor,|| |
Polymorphic light eruption (PLE) is a common, intermittent, UVR-induced eruption characterized by nonscarrring, erythematous itchy papules, plaques or vesicles over exposed skin. The severity of the disease is maximum during spring and summer and young females are more commonly affected than males. Although all ethnic groups are affected, PLE has been found to be most common in temperate regions, affecting upto 10-20% of the population., The disease is not uncommon in tropical countries. However, its exact incidence in India is unknown.
Over the last one year we have been seeing quite a number of cases of PLE in Kota. Of 3583 registered cases seen in the Skin out patient department of our hospital during October 1994 to November 1995, 384 (10.71%) cases were of PLE. This is quite a high incidence. The first author (SD) has the experience of working in Calcutta and Chandigarh but has not seen such a large number of case of PLE in those two cities. Neither such high incidence of this disease has been reported from other parts of India.
Kota is situated in the south-eastern part of Rajasthan with the maximum temperature varying between 47°-50°C during summer and minimum temperature 6°-9°C during winter. Sunlight is quite plentiful almost throughout the year except during the months of July and August.
The increased availability of UVR could be responsible for such high incidence of PLE. However, we do not come across other types of idiopathic photodermatoses like actinic prurigo, juvenile spring eruption, solar urticaria more frequently in our population. Therefore, some factor other UVR must be playing a significant role in precipitating the disease in this region.
