BACKGROUND: Although halo nevus (HN) is frequently observed, the relationship between vitiligo and HN in children has rarely been investigated. OBJECTIVES: To investigate the association between HN and vitiligo in children and understand if HN/HNi might be a risk factor for vitiligo. METHODS: Ninety-eight patients with only HN/HNi and 27 with HN/HNi and vitiligo were investigated for number and localization of HN/HNi, family history for HN/HNi and vitiligo and personal and family history for autoimmune or other diseases. A follow-up telephone interview was performed to investigate the evolution of HN/HNi and the possible onset of vitiligo and/or other diseases. RESULTS: In the HN/HNi and vitiligo group, HN/HNi and vitiligo had started almost simultaneously in 11 children; in nine, the onset of HN/HNi was followed by vitiligo after 6 months to 5 years; seven patients presented vitiligo first and HN/HNi after 3-9 years. Patients with associated vitiligo had, significantly more often, multiple HNi and a positive personal and/or family history of autoimmune thyroiditis compared with those with only HN/HNi. Follow-up longer than 5 years was available in 54/98 patients with only HN/HNi; two of them, both with multiple HNi, developed vitiligo. After follow-up, multiple HNi were noticed in 18/52 patients without vitiligo and in 9/11 of those in whom HN/HNi heralded vitiligo (s.s.). CONCLUSIONS: In patients with multiple HNi, the risk of vitiligo and other autoimmune diseases seems to be higher than in pediatric patients with a single HN; clinicians should pay particular attention to children with multiple HNi and personal or family history of autoimmune diseases.

Abstract

BACKGROUND: Although halo nevus (HN) is frequently observed, the relationship between vitiligo and HN in children has rarely been investigated. OBJECTIVES: To investigate the association between HN and vitiligo in children and understand if HN/HNi might be a risk factor for vitiligo. METHODS: Ninety-eight patients with only HN/HNi and 27 with HN/HNi and vitiligo were investigated for number and localization of HN/HNi, family history for HN/HNi and vitiligo and personal and family history for autoimmune or other diseases. A follow-up telephone interview was performed to investigate the evolution of HN/HNi and the possible onset of vitiligo and/or other diseases. RESULTS: In the HN/HNi and vitiligo group, HN/HNi and vitiligo had started almost simultaneously in 11 children; in nine, the onset of HN/HNi was followed by vitiligo after 6 months to 5 years; seven patients presented vitiligo first and HN/HNi after 3-9 years. Patients with associated vitiligo had, significantly more often, multiple HNi and a positive personal and/or family history of autoimmune thyroiditis compared with those with only HN/HNi. Follow-up longer than 5 years was available in 54/98 patients with only HN/HNi; two of them, both with multiple HNi, developed vitiligo. After follow-up, multiple HNi were noticed in 18/52 patients without vitiligo and in 9/11 of those in whom HN/HNi heralded vitiligo (s.s.). CONCLUSIONS: In patients with multiple HNi, the risk of vitiligo and other autoimmune diseases seems to be higher than in pediatric patients with a single HN; clinicians should pay particular attention to children with multiple HNi and personal or family history of autoimmune diseases.
