Abstract

Abstract:  We performed a retrospective study covering a 10-year period (January 1997–January 2007) on children referred to our unit or followed up for Becker’s nevus (BN). The aim of this study was to better define the characteristics of BN in childhood, when this hypermelanosis is more frequent than the limited number of studies might suggest. Our data show that BN in children has predilection sites similar to those in adults, but hypertrichosis is rarer. Sun exposure does not appear to play an etiopathogenetic role. The higher incidence in men reported in adult case studies was not found in children. During and after puberty, androgenic stimulation is known to play a pathogenetic role in BN, especially in men, but our cases were mostly younger than 6 years old.
