In recent years, the Department of Dermatology has summarized through clinical practice a new method of laser treatment for non-venereal skin warts (common warts, plantar warts, paronychium warts), which is effective and has few side effects and is suitable for patients who have failed other treatments. In order to better serve patients with intractable skin warts and relieve their pain, we sincerely seek patients who have received four failed cryotherapy treatments. For eligible patients, the Department of Dermatology provides the following benefits and facilities: 1 partial waiver of laser treatment fees; 2 priority for consultation and treatment; 3 staff regularly contact patients to understand the treatment effect and guide patients’ recovery. Eligible patients are welcome to visit our department.
