Summary

Melanocytic neoplasms comprise one of the most common tumours encountered in the skin of children. Although the vast majority of pigmented skin lesions in children are benign and of no consequence, some may herald a phenotype with an increased predisposition towards melanoma, others may be potential precursors to melanoma, while a few will unfortunately be malignant. The challenge for clinicians is to distinguish between these melanocytic lesions. Unfortunately, relying purely upon the primary clinical morphology can be limiting, since melanomas arising in children often do not manifest a clinically ominous appearance. However, the use of dermoscopy, a non-invasive, in vivo technique, can aid in the evaluation of skin lesions by allowing the physician to visualize colours and structures located at the epidermis, dermoepidermal junction and upper dermis that are otherwise not routinely visible to the unaided eye. This chapter will focus on the key dermoscopic features of melanocytic lesions commonly encountered in the paediatric population, including congenital melanocytic naevi, acquired naevi, halo naevi and Spitz naevi.
