Vitiligo and psoriasis are common dermatoses with autoimmune pathomechanisms. There are numerous case reports on the coexistence of these two conditions but only a few have reported the colocalization of lesions. Moreover, to our knowledge, only one case of concurrent segmental vitiligo and plaque type psoriasis has been documented. Several theories have been put forward however the exact pathogenesis of the association between these two remain unknown.
