Certain racial groups may also be more genetically predisposed to develop psoriasis.Higher prevalences seem to be found in Scandinavia (3% to 4.8%), Malaysia (4% to 5%), East Africa (1.25% to 3%), and South Africa (4% to 5%), and lower prevalences are seen in West Africans (0.3% to 0.8%), African Americans (0.45% to 1.3%), Southeast Asians (0.4% to 2.3%), Indians and East Asians (~0.3%), and the indigenous populations of the Americas (nearly absent).The clinical features of psoriasis are similar across racial groups; however, darker skin phototypes show a tendency toward violaceous plaques, gray scale, and postinflammatory dyspigmentation.The treatment of psoriasis is similar across racial groups. Traditional medicine is used by certain populations. SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/04/18 UR - accessmedicine.mhmedical.com/content.aspx?aid=1161545336 ER -
