The diagnosis of vitiligo is usually straight forward for a Dermatologist. Vitiligo presents as pale white patches on areas such as the face, hands, feet, trunk and genital areas. If the scalp or eyebrows are involved, the affected hairs maybe white. Using a dermatoscope or microscope, Specialists can take note of subtle signs such as pigmentation of the hair follicle, and this may help give a prognosis for treatment. In 95% of cases the diagnosis of vitiligo is a clinical one, and no tests are needed.
