Total body naevi counts have been performed on 3931 Italian subjects aged 5 to 79 years (2063 males and 1868 females). Only naevi greater than or equal to 2 mm in diameter were recorded. The total mean naevi count was 15 (15 for males, 14 for females); in the first decade of life the count was 8, rising rapidly in the second decade to a mean of 18 and was 22 in the third decade. Thereafter the frequency of naevi declined with age; in the eight decade the number was similar to that seen in children. The association between total naevi count and place of birth of subjects or their parents was not significant. The frequency of naevi varied according to body site: the most common site was the trunk (6 naevi), the next most affected site was the upper arm (4 naevi). Distribution by eye colour, hair colour and number of naevi showed an increase in subjects with blue or green eyes and red or fair hair. High associations were found between large numbers of acquired melanocytic naevi and pale skin. Skin types 1 and 2 had a higher melanocytic naevi count than skin types 3 and 4.
对3931名年龄在5至79岁的意大利受试者（2063名男性和1868名女性）进行了全身痣计数。仅记录直径大于或等于2毫米的痣。痣的总平均计数为15颗（男性为15颗，女性为14颗）；在生命的第一个十年中计数为8颗，在第二个十年中迅速上升至平均18颗，在第三个十年中为22颗。此后，痣的出现频率随年龄下降；在第八个十年中，数量与儿童时期相似。痣的总计数与受试者或其父母的出生地之间的关联不显著。痣的出现频率因身体部位而异：最常见的部位是躯干（6颗痣），其次受影响的部位是上臂（4颗痣）。按眼睛颜色、头发颜色和痣的数量分布显示，蓝眼睛或绿眼睛以及红头发或浅色头发的受试者数量有所增加。大量后天性黑素细胞痣与浅色皮肤之间存在高度关联。1型和2型皮肤的黑素细胞痣计数高于3型和4型皮肤。
