Solar (senile) purpura is commonly seen in elderly people and occurs because of actinic damage in skin that is chronically exposed to sunlight. Lesions occur bilaterally over the extensor aspect of the forearms and dorsae of the hands. The lesions occur spontaneously or following minor trauma. Individual lesions last from 1 to 3 weeks, but do not exhibit the typical color changes of resolving purpuric lesions, probably because of the absence of an inflammatory response.1
We describe solar purpura restricted to the extensor aspect of the right forearm in two taxi drivers (driving right-hand drive vehicles) and attribute it to asymmetric photodamage to the right side of the body.
Report of Cases.
Two male taxi drivers, 45 and 50 years old, respectively, presented with similar complaints of recurrent asymptomatic bruising over the extensor aspect of the right forearm only for the past 1 and 1.5 years, respectively.
