The body site distribution of melanocytic naevi in 6-7 year old European children

Abstract

The number and size of melanocytic naevi are the main predictors of cutaneous melanoma. Naevus development per unit of skin surface is greatest during childhood. We assessed the body distribution of naevi 2-4.9mm and ≥ 5 mm in 649 European children aged 6-7 years old from Brussels (Belgium), Bochum (Germany), Lyon (France) and Rome (Italy). The numbers of naevi 2-4.9 mm and naevi ≥ 5 mm were strongly correlated, especially on the trunk. For naevi 2-4.9 mm, the highest relative densities were found on the face, back, shoulders and the external surface of the arms. The lowest relative densities were found on the hands, legs, feet and abdomen. The relative density of naevi ≥ 5 mm was higher on ..
