Imiquimod for plantar and periungual warts.

Plantar and periungual warts are notoriously difficult to eradicate. Two cases of nongenital warts in teenage girls are presented. Imiquimod was used in combination with cryotherapy for the periungual warts and with occlusion for the plantar warts. Both cases showed complete resolution and that imiquimod may be more effective on thicker keratinized (nongenital) skin when occluded or used in combination with cryotherapy.
