BACKGROUND: The association of atypical nevi with melanoma and other forms of skin cancer has not been clearly defined.
METHODS: We studied 631 patients with first lifetime diagnosis of mild, moderate or severely atypical nevus from 2000 through 2005, identified through a population-based approach.
RESULTS: Age at first diagnosis differed significantly between men and women (p<.001). Incidence rates peaked in the second through fourth decades in women and in the third, sixth and seventh decades in men. From 2000 through 2005, the overall age- and sex-adjusted incidence rate of all degrees of atypical nevi was 76.0 per 100,000 person-years. There were no statistically significant associations identified between the degree of atypia and the future development of basal cell carcinoma, squamous cell carcinoma or MM (p = 0.51, p = 0.28 and p = 0.19, respectively).
CONCLUSION: There is no association between atypical nevi and the subsequent development of non-melanoma skin cancer and MM. Incidence rates of atypical nevi are higher among younger women and older men. The association between degree of atypia and malignant melanoma warrants further study.
