Although the outcomes of various treatment modalities for vitiligo have been studied extensively, the influence of the participant%26apos;s characteristics on treatment response has not been thoroughly investigated. Therefore, we retrospectively investigated treatment effects and their association with clinical characteristics in Japanese patients with vitiligo. The charts of patients with vitiligo treated in our institution were reviewed. Clinical response was evaluated as a marked response rate, defined as repigmentation in %26gt;75% of the initial lesional area. 162 patients were treated with phototherapy, while 69 were treated with topical mono-therapy. The patients treated with phototherapy and those treated with both phototherapy and topical treatment demonstrated significantly higher clinical response rates compared to patients treated solely with topical mono-therapy (marked response rate: 19.1% vs. 5.8%, P%26lt;0.05; and 23.5% vs. 5.8%, P%26lt;0.01, respectively). Among the phototherapy-treated patients, younger subjects (15 years old) were more responsive to phototherapy compared to older patients (37.0% vs. 15.6%; P=0.015). The disease subtypes did not affect treatment response. In conclusion, phototherapy appears to have a therapeutic effect superior to topical mono-therapy on both focal and generalized vitiligo, especially in younger patients. Thus, any type of psychosocially devastating lesions in a pediatric patient may be a good target for phototherapy.
