My group's study1 demonstrates that the number of melanocytic nevi larger than 2 mm in diameter is higher in children aged between 8 and 9 years who were exposed to neonatal phototherapy than in those who were not exposed. In a multivariate analysis, we have studied the respective roles of both sun exposure and neonatal phototherapy (Table).
