We thank Naldi et al for examining their data for relationships between red hair color, freckles, nevus count, and melanoma risk.
When we submitted our finding to the ARCHIVES 1 year ago that young children with red hair have more freckles but fewer melanocytic nevi than those with other hair colors, a reviewer claimed that this relationship has been known for 20 years. As our requests for data supporting this statement went unanswered, we take this opportunity to ask anyone aware of the reference (or name of the investigator) that established this knowledge 20 years ago to please bring this information to our attention.
