Abstract

The naevus profile was examined in a Swedish population that was randomly selected from a census file. The participation rate was considered high at 82%. The number of common naevi (CN) and the prevalence of dysplastic naevi (DN) were investigated in 379 subjects (aged 30-50 years). The mean total body count of CN greater than or equal to 2 mm was 67 (range 1-300). As many as 22% of the population had 100 naevi or more and only 18% had less than 25. The counts were not influenced by age or sex. DN were diagnosed clinically in 18% (CI 14-22%) of the subjects and histologically in 8% (CI 5-11%). Subjects with dysplastic naevi had a significantly larger number of common naevi and a more sun-sensitive skin type than subjects without DN, P less than 0.001.

摘要

在从人口普查档案中随机选取的瑞典人群中检查痣的情况。参与率被认为较高，为82%。在379名年龄在30至50岁之间的受试者中调查了普通痣（CN）的数量和发育异常痣（DN）的患病率。直径大于或等于2毫米的CN的平均全身计数为67颗（范围为1至300颗）。多达22%的人群有100颗或更多的痣，只有18%的人痣数少于25颗。计数不受年龄或性别的影响。临床上诊断为DN的受试者占18%（置信区间14 - 22%），组织学诊断为DN的占8%（置信区间5 - 11%）。与无DN的受试者相比，有发育异常痣的受试者普通痣数量显著更多，且皮肤类型对阳光更敏感，P值小于0.001。
