摘 要:Objective: To evaluate the prevalence of common acquired melanocytic nevi and its relationship with pigmentary characteristics and severe sunburns in children. Design: Cross- sectional study. Setting: Kaunas city, Lithuania (latitude of 55° 55 minutes). Patients: A random sample of 484 children aged 1 to 2 years, 4 to 5 years, and 9 to 10 years and adolescents aged 14 to 15 years. Interventions: A questionnaire that provided information about the history of sunbathing and skin type. Main Outcome Measures: Atypical melanocytic nevi were defined according to the clinical criteria of the ABCDE rule. Results: The median number of all common acquired melanocytic nevi was 12 in boys and 11 in girls; the median number of melanocytic nevi 2 mm or larger in boys and girls was 4. Twenty- seven percent of children experienced severe sunburns more than once. After adjustment for age and sex, it was found that children who had severe sunburns in summer and skin type I had a higher density of all melanocytic nevi and melanocytic nevi 2 mm or larger. The prevalence of atypical melanocytic nevi was 7% in all children and was age dependent (age 4- 5 years, 1% ; 9- 10 years, 4% ; 14- 15 years, 16% ). Three percent of children had congenital melanocytic nevi. Conclusions: The total number of common acquired melanocytic nevi in children increased with age. There was a positive association between severe sunburns, the tendency of the skin to burn, and the number of all melanocytic nevi and nevi 2 mm or larger.
