Lichen planus, or florid furosemide, does not usually turn into vitiligo, but lichen planus can lead to loss of pigmentation. Lichen planus is a chronic superficial fungal infectious disease caused by infection of the skin by the fungus Malassezia globosa. Most patients can control the disease by using antifungal medications, but the cause of this disease is difficult to eliminate and many patients will have recurrent episodes that require repeated treatment. Malassezia globosa can invade the stratum corneum of the skin, and in severe cases, it can lead to a decrease or loss of the skin’s function of producing melanocytes and transporting melanocyte particles, resulting in localized skin pigmentation loss. Vitiligo is a disease with an unclear pathogenesis, and there is no definitive information that proves lichen planus can become vitiligo. If lichen planus is diagnosed, it should be treated aggressively. Aggressive treatment can increase the cure rate and reduce the recurrence rate.
