ABSTRACT
INTRODUCTION:
Vitiligo is a skin disorder characterized by achromic macules (white) on the skin and/or mucous membranes, which affects 0.5-2% of the population. Few publications address a vitiligo epidemiological profile worldwide. In Brazil there are only studies in children.OBJECTIVE:
To assess the clinical and epidemiological profile of individuals affected by vitiligo and to evaluate behavior of the disease in different age groups. MATERIALS ANDMETHODS:
We conducted a retrospective cross-sectional study in 669 patients with vitiligo from January 2001 to May 2006, who attended the Faculty of Medicine of ABC, located in the metropolitan region of São Paulo, Brazil.RESULTS:
There was a predominance of females (62.2%) and adult age group (62.5%), with higher prevalence peaks between the second and third decades of life (18.3% and 16.9%, respectively). The most frequent phototype in skin was III (49.9%). Lesions began on the face most commonly in children and adolescents (32.6%) and the elderly (23.3%), and on hands in adults (24.0%). There was a higher prevalence of segmental vitiligo in children and adolescents (36.4%), compared with adults (11.3%) and the elderly (6.7%), and vitiligo with stable evolution was proportionately more frequent in childhood and adolescents (46.2%) than in adults (32.5%) and elderly (36.7%).CONCLUSIONS:
Our findings are similar to other countries, mainly regarding the higher prevalence of segmental vitiligo and vitiligo with stable development among children and adolescents.
