Vitiligo Associated With Pegylated Interferon and Ribavirin Treatment of Patients With Chronic Hepatitis C

Vitiligo is an autoimmune disease characterized by depigmented patches and macules. It is associated with many autoimmune diseases, the most common of which is thyroid diseases. The association between Interferon (IFN) therapy and vitiligo is rarely reported in the literature, despite its common usage in many diseases particularly hepatitis C viral infection (HCV). We report four cases of vitiligo that appeared after treating HCV with pegylated IFN.
