Abstract
Background: Childhood vitiligo differs from adult-onset vitiligo for several features, but is basically the same disease, with a potentially better regenerative capacity of the melanocytic lineage. The exact prevalence of vitiligo in the pediatric age group is unknown but the figure of approximately 25% of onset of vitiligo before the age of 10 years obtained in Denmark seems correct. The mean age of onset in pediatric series varied among different studies from 4 to 8 years, but very early onset, as young as 3 months, is acknowledged, whereas congenital vitiligo is usually piebaldism misdiagnosed as vitiligo. The existence of true congenital vitiligo remains controversial. In fair-skinned individuals, vitiligo patches are usually detected only after the first exposure of the skin to sunlight, following the first summer of life. Girls predominate in reported pediatric series, but population-based studies do not confirm a sex bias.
Aim of the Work: The aim of our study is to study the pattern and distribution of vitiligo among children and comparing it with adults.
Patient and Methods: The present study represents a cross sectional study which was carried out on 483 patients with vitiligo attending dermatology clinic of Al-Demerdash hospital and Kobry Al Qubba military hospital that were diagnosed clinically.
Results: In the present study the number of female patients was more than males. This is in accordance with Lanella et al. who suggested that females complain earlier and more frequently because vitiligo is considered a cosmetic problem. Some studies have found that vitiligo is more common in males.
