Flat warts, also known as verrucae planae, are commonly treated using methods that target the virus that causes them and promote the sloughing of the wart tissue. Tretinoin cream is a topical retinoid that can help to exfoliate the skin and reduce the size and appearance of various types of warts, including flat warts. Its mechanism involves promoting cell turnover and preventing the proliferation of the virus-infected keratinocytes.

Liquid nitrogen is an effective cryotherapy method that involves freezing the wart tissue. This method causes cell destruction through the formation of ice crystals inside the wart, leading to its eventual fall-off as the skin heals. The combination of tretinoin and liquid nitrogen offers a dual approach to treating flat warts effectively.

The other options, while they may involve methods to treat different types of warts or skin lesions, are less commonly indicated for flat warts specifically. Using electrocautery or surgery often pertains to more substantial warts or other dermatological conditions, while therapies like imiquimod are primarily reserved for different wart types or conditions. Similarly, laser therapy is typically utilized for more severe cases or other skin lesions, rather than specifically for flat warts.
