As paediatric patients with multiple halo naevi are at higher risk of developing vitiligo or other autoimmune diseases than those with one halo naevus, these patients may benefit from clinical monitoring. Discussion Halo naevus, also described as leucoderma acquisitum centrifugum or Sutton naevus, is a melanocytic naevus with a surrounding rim of depigmentation that can develop from an acquired or congenital melanocytic naevus.[1] The lesion typically progresses through multiple stages, including central brown naevus with surrounding depigmentation, depigmentation of the central papule and regression of the papule with persistence of surrounding depigmentation. Halo naevi may last 10 or more years, however, a large percentage of these undergo spontaneous repigmentation.[2] Halo naevi are often seen in children and adolescents although they may occur in older adults.
