Becker’s naevi are associated with neurological abnormalities - supplementary image with composite pattern and localization of all Becker’s Naevi

Composite pattern and localization of all Becker’s Naevi, constructed by overlaying the skin patterns of each child in the cohort onto a single body map. Darker areas are therefore more frequently affected. Of note upper and lower body areas are equally affected contrary to popular conception, and the pattern markedly spares the anterior and posterior central torso.
