Vitiligo is a common acquired disorder that has an estimated incidence of 1-4% [1]. It is inherited either polygenic or autosomal dominant, with incomplete penetrance and variable expression. Approximately in half of the patients vitiligo developed before the age of 20 [2]. It is characterized by a fairly symmetric pattern of circumscribed macules and patches of amelanosis. Vitiligo has a considerable social and psychological effect on patients because of alteration of appearance [3,4]. On the other hand chronic urticaria not only affect the appearance but involves physical discomfort and others view skin lesions as stigmatizing [5,6].
