What's already known about this topic?
- In order to phenotype or identify at-risk patients in a rapid and practical manner for large-scale studies or screening campaigns, naevus counts on selected body sites can be used as a proxy for total body naevus count.
- The correlation between site-specific and total body naevus counts appears to be highest for the arms, although results have not been consistent across studies or sexes.
What does this study add?
- Our results further support the arm as a practical and reliable site to estimate the total naevus count when screening or phenotyping large populations.
- Cut-off values of 6, 8 and 11 naevi on the right arm best predicted total naevus count above 25, 50 and 100, respectively.
- These threshold values provide dermatologists with various degrees of patient risk selection and can be adjusted on an individual basis.
