an acquired depigmentation disorder that occurs due to melanocyte destruction.
Although the etiology of vitiligo is unknown, it is likely partially immune-mediated, as it often occurs in those with a concomitant autoimmune disease.
Although vitiligo typically has a more generalized distribution, a subset of patients have lesions that affect only the genital or oral mucosa.
Patients with vitiligo develop flat, hypopigmented macules with distinct borders that can expand and coalesce. These lesions do not have overlying scaling or inflammation; therefore, patients are often asymptomatic (eg, normal vulvar architecture) and the vitiligo may be an incidental finding.
Diagnosis is clinical
Treatment is dependent on disease severity and includes corticosteroids (which can stabilize disease progression) and phototherapy (which may help with repigmentation).
