S100B is a dual function protein released from epidermal melanocytes in response to injury. It considered a possible marker of disease activity in both malignant melanoma and vitiligo.<\/jats:p><\/jats:sec><jats:sec><jats:title>Aim of the study<\/jats:title><jats:p>To estimate the serum level of S100B level in vitiligo patients and correlate its level with disease activity and various disease parameters.<\/jats:p><\/jats:sec><jats:sec><jats:title>Patients and methods<\/jats:title><jats:p>Sixty vitiligo patients and 60 healthy volunteers as controls were included in the study.
