Xeroderma pigmentosum (XP) is a rare, autosomal recessive disorder. It is a disorder of defective UV-radiation induced damage repair that is characterised by photosensitivity with easy skin burning following minimal sun exposure, early freckling and development of lentiginous pigmentation along with other features of poikiloderma (areas of hypopigmentation, hyperpigmentation, telangiectasias and atrophy) and a propensity for developing skin cancer at an early age.1
