The approach adopted for differential diagnosis of melanomas and nevi considers diverse morphologic characteristics intrinsic to the lesions, that is, shape, size, and symmetry in total independence of pigmentation, and proposes that this information can be evaluated quantitatively and separately by morphometric procedures with statistically valid independent numeric variables that guarantee objectivity and, from a method point of view, consistency. The results show that the differential diagnosis on malignant and benign lesions is made on five variables, which all describe the fine irregularities of the contour and have a high significance in comparing melanomas to nevi. The multivariate discriminant analysis demonstrates the ability of the analytic variables to discriminate 88% of the lesions, rising to 90% if two-dimensional variables are included.

Regression of congenital melanocytic nevi is usually accompanied by the halo phenomenon and is considered a rare event. OBJECTIVE. A 15-year-old woman presented for the evaluation of multiple halo nevi. She had on her trunk a figure-of-eight pigmentary lesion, which had been developed after the coalescence of two distinct congenital melanocytic nevi. Close to the indentation between the two portions of the lesion, there was an achromic rounded area, extending from the perinevic skin to the nevus, causing its partial regression. METHODS AND MATERIALS. Dermoscopic examination disclosed a globular and homogeneous pattern, which was irregularly present at the edge of the achromic area. The histopathologic diagnosis was compound congenital melanocytic nevus with an eccentric area of regression.
