Vagarious successful treatment of recalcitrant warts in combination with CO2 laser and imiquimod 5% cream.

ABSTRACT

BACKGROUND: Imiquimod 5% cream is widely regarded as a safe and effective option when treating recalcitrant warts, owing to the ointment's negligible side effects. However, our observations highlighted case of a patient incurring severe adverse reactions due to application of the cream, although the treatment proved successful in curing recalcitrant warts which had developed on the external auditory canal and external ear. METHODS: All lesions were entirely removed with short-pulsed CO2 laser. As soon as the wound-healing process was completed, imiquimod 5% cream was self-applied on the healing wounds once daily for 5 days per week in a total of 2 weeks. RESULTS: The patient appeared normal after the CO2 laser treatment and experienced severe redness, itching, exudation, and incrustation after a 2-week imiquimod 5% cream therapy. All lesions showed no recurrence during the 12-month followed-up process. CONCLUSIONS: We concluded that a feasible treatment modality to cure recalcitrant cutaneous warts is in combination of CO2 laser and imiquimod. Immunoenhancement plays an important role in the treatment of recalcitrant warts.
