The number of total body nevi is a major risk marker for malignant melanoma. No previous study has evaluated the accuracy of whole body large nevus (> or = 5 mm) self-counts.
Our purpose was to evaluate the accuracy of large nevus self-counts by sex, age, educational level, body site, family history of skin cancer, and nevus characteristics.
Self-counting of large nevi by 125 patients was compared with physician counting, with attention to nevus characteristics.
Overall, 79% of the self-counts agreed to within +/- 3 nevi of the physician's count. Analysis of variance revealed that the presence of nonpigmented or flat nevi significantly increased the chance of subject undercount, as did male sex.
Self-counts of large nevi are comparable to physician's counts and may be useful for melanoma screening.
全身痣的数量是恶性黑色素瘤的主要风险指标。此前尚无研究评估全身大痣（≥5毫米）自我计数的准确性。
我们的目的是评估按性别、年龄、教育程度、身体部位、皮肤癌家族史和痣的特征进行大痣自我计数的准确性。
将125名患者的大痣自我计数与医生计数进行比较，并关注痣的特征。
总体而言，79%的自我计数与医生计数相差在±3颗痣以内。方差分析显示，无色素或扁平痣的存在显著增加了受试者计数不足的可能性，男性也是如此。
大痣的自我计数与医生的计数相当，可能有助于黑色素瘤筛查。
