Association of Vitiligo and Response in Patients with Metastatic Malignant Melanoma on Temozolomide

Vitiligo-like lesions, although rare, are believed to be a prognostic factor in malignant melanoma. While a predictive role for such lesions was shown with immunomodulatory therapies, this relation was not demonstrated with temozolomide. We present 3 patients with metastatic malignant melanoma who developed vitiligo-like skin lesions accompanying good response to treatment and prolonged survival. Onset of vitiligo-like lesions with temozolomide in metastatic malignant melanoma may predict long-term response for this treatment.
