ABSTRACT
Actinic prurigo (AP) is an uncommon, acquired, idiopathic photodermatosis that particularly affects American Indians, and less frequently Caucasian and Asian populations. A variety of descriptions have been used in the past, including Hutchinson’s summer prurigo and hereditary polymorphic light eruption (PLE). The term actinic prurigo was introduced in 1961 by Lopez Gonzalez.1 The disorder has previously been considered to be a variant of PLE, but sufficient differences exist for it to be recognized as a distinct disease entity.
