WHETHER NEVI SPILI (NS), also known as speckled lentiginous nevus, are congenital or acquired is currently under debate. In the article by Schaffer et al,1 the authors describe 10 patients, each of whom had NS that was present at birth or within the first month of life. The authors contend that because of the clinical history and their spotted appearance, these lesions represented NS that were congenital rather than acquired.
