Hamel R, Mohammad TF, Chahine A, et al. - Via conducting a retrospective chart review at four institutions’ general dermatology clinics using diagnoses consistent with the International Classification of Disease (ICD), Ninth and Tenth Revisions, codes related to photodermatoses between August 2006 and August 2016, researchers contrasted the distribution of photodermatoses between Whites and Blacks at four academic medical centers in the USA. In total, 9,736 charts were manually reviewed and classified. One thousand eighty patients with photodermatoses were identified. The authors found significantly higher proportions of polymorphous light eruption in Blacks, and higher proportions of photoallergic contact dermatitis, phototoxic drug eruptions, phytophotodermatitis, porphyrias, and solar urticaria in Whites.
