Dermoscopic patterns of nevus sebaceous – captured at different stages of evolution

The nevus sebaceous (NS) is a hamartoma of the skin and its adnexa pertaining to the group of organoid nevi. NS presents at birth and grows proportionally with the growth of the child. During adulthood, secondary neoplasms may arise from NS. Though the diagnosis of NS is mainly clinical, dermoscopy can be used as a diagnostic aid. Dermoscopy characteristically shows yellow globules, white, grey lobules arranged in clusters in a yellow background in a NS during childhood. Dermoscopic assessment will assist in diagnosis; and also, in assessing and monitoring the evolution of NS. It is also helpful in detecting malignant transformation of NS early, to arrange timely surgical excision in dermatological practice especially in resource poor setting.
