Actinic cheilitis (AC) is a pre-malignant inflammatory reaction of the lips caused by continuous exposure to solar rays. The aim of this study was to assess the prevalence of AC in a population of sugarcane workers in Brazil. 1,539 individuals who were exposed to the sun during working hours and 150 individuals who were not exposed were screened for clinical signs of AC. The sample was classified according to years of exposure to the sun, ethnicity, gender smoking and severity of the lesion. A 9.16% (n= 141) prevalence of AC was observed among the population which had been exposed to the sun. The prevalence of AC lesions was significantly higher among individuals who had been exposed to the sun for more than 10 years than among those who had been exposed for less than 10 years, and among Caucasians and males than non-Caucasians and females. It was concluded that the severity of the lesions was associated with time of exposure to the sun.
