Vitiligo
Key Points
Some cases of vitiligo may involve genetic mutations or autoimmune disorders. Vitiligo can be focal, segmental, or, rarely, generalized. Diagnose by skin examination and consider testing with complete blood count, fasting blood glucose, thyroid function tests, and antithyroid peroxidase antibodies. Consider treatments such as topicalcalcipotrieneplusbetamethasonedipropionate, corticosteroid topical monotherapy, narrowband UVB, or a calcineurin inhibitor (tacrolimusandpimecrolimus). Janus kinase inhibitors are an emerging treatment modality for vitiligo.
