Trichrome vitiligo consists of an intermediate zone of hypopigmentation located between the depigmentation center and the normal unaffected skin. Previously, trichrome vitiligo was described in non-segmental vitiligo. Here, we report two cases of trichrome vitiligo that showed a poor response to phototherapy or systemic steroid. These findings suggest that trichrome vitiligo in segmental type seems to be an active lesion resistant to medical treatment.
