In patients with small- or medium-sized congenital nevi, peripheral location of the suspicious area and negative network may be the strongest dermatoscopic predictors of melanoma, researchers reported in a study published in the Journal of the American Academy of Dermatology.
The investigators screened the databases of 3 skin cancer referral centers to identify small- or medium-sized congenital nevi that were excised or biopsied to rule out melanoma developing in the nevus. Univariate and multivariate logistic regression were used to calculate crude and adjusted odds ratios, respectively.
