Plantar and common warts can be cured with great efficacy by the intralesional injection of bleomycin using the jet injector. Traditional keratolytic treatment and electro-desiccation are also still in use. Condyloma acuminata respond to podophyllin combined with cryotherapy. It is advisable to use the CO2 laser in more extensive infections. Interferon injections also may be helpful in these cases. Plane warts can be treated by tretinoin and 5-fluorouracil. In case of diffuse verruca sensitization with diphenylcyclopropenone can be considered.
