To determine the risk factors of naevus fusco-caeruleus zygomaticus, a case-control study was conducted in 100 cases. The selection of major risk factors was through logistic regression and chi 2-test. It was suggested that the high exposed rate in the family history of objectives was related to "genetic susceptibility". Histories of using cosmetics and exposure to ultraviolet ray were identified as environmental risk factors. However, there was no single factor that could completely explain the etiology of naevus fusco-caeruleus zygomaticus. We believe that coordinating effects of both susceptibility in genetics and environmental risk factors may play important roles in the pathogenesis of naevus fusco-caeruleus zygomaticus. Thus combined research on the location of gene mutation with environmental factors is important in the discovery of the etiology of naevus fusco-caeruleus zygomaticus.
