Résumé

Background: 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 (≥ 5 mm) self-counts.

Objective: 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.

Methods: Self-counting of large nevi by 125 patients was compared with physician counting, with attention to nevus characteristics.

Results: 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.

Conclusion: Self-counts of large nevi are comparable to physician's counts and may be useful for melanoma screening.
