Punctate leukoderma – http://id.who.int/icd/entity/425510384

A dermatosis associated with both psoralen photochemotherapy and UVB phototherapy in which multiple round or oval sharply demarcated punctate macules measuring 0.5 – 1.5 mm in diameter form principally on the fronts of the shins and on the extensor aspects of the arms. It is attributed to phototoxic damage to melanocytes.
