ABSTRACT
Vitiligo is a common acquired disease that affects 1 to 2% of the population. It is characterized by one or multiple patches of depigmented skin (Fig. 1). Histologically there is an absence of cutaneous melanocytes. In addition, lymphocytic infiltrates have been described in the involved border and uninvolved skin of patients (1). The disorder may begin at any age but peak frequencies occur in the second and third decade. Females are affected more often than males. Studies show a familial incidence in 25 to 30% of patients with vitiligo. The disease can be precipitated by severe emotional stress, physical illness, bacterial and viral infections, sunburn, and physical trauma.
