Disseminated superficial actinic porokeratosis, which was described in 1966, is characterized by small, atrophic patches with distinctive keratin rims that occur on sun-exposed areas of the extremities, shoulders, and back. The diagnosis is based on the histopathologic finding of a cornoid lamella, absence of a granular layer, and often a thin epidermis. It is associated with exposure to ultraviolet radiation. Gene studies suggest a pathway defect in which several mutations in keratinocyte proliferation and differentiation lead to development of porokeratosis.
