Abstract
- Although the coexistence of vitiligo and psoriasis is well known and considered not unusual, psoriasis localized exactly on vitiliginous lesions has been rarely reported. We report a 13-year-old girl with erythematous scaly plaques localized only on the depigmented vitiliginous patches after narrow-band UVB therapy. Biopsy samples were taken from the areas where the new erythematous plaques occurred. Considering the clinical findings and the biopsy results, our case corresponds to psoriasis co-localized with vitiligo. After the patient discontinued phototherapy and started oral cyclosporine, the psoriatic lesions improved. We report a rare case of psoriasis arising strictly on vitiligo lesions.
