Pigmented lesions: when should I worry?

Abstract

Abstract Pigmented lesions in children are very common. The majority are benign melanocytic naevi that develop during childhood but, rarely, sinister lesions such as melanoma and atypical Spitz naevi can also occur. The group of benign pigmented lesions includes benign acquired and congenital melanocytic naevi, blue naevi, halo naevi and Spitz naevi. This article will enable clinicians to be aware of the concerning features, use the ABCDE criteria appropriately, understand how to use the available diagnostic tools and when to refer to a Paediatric Dermatology department for further opinion and management.
