Abstract
Previous studies have discussed the low prevalence of psoriasis among indigenous peoples of South America. The state of Roraima, Brazil, where the present study was performed, is crossed by the equator line. It is likely that key factors for the absence of psoriasis in this indigenous population include genetic factors, a lack of environmental triggers and high sun exposure.
