Intralesional acyclovir will be prepared by diluting 1 ampoule of Acyclovir 250mg into 3.5ml of saline solution to achieve a concentration of approximately 70mg/ml. Then 0.1ml will be injected intra-lesionally into the base of the wart. Any hyperkeratotic lesions should be pared before the treatment. This process will be repeated every 2 weeks for 5 sessions, and can be discontinued if complete resolution is achieved early.

Patients allocated to Group B will undergo cryotherapy using a liquid nitrogen spray gun. Any hyperkeratotic lesions should be pared before the treatment. Two freeze-thaw cycles will be applied each session, the spray gun should be held 1cm away from the wart and maintained until the wart and the 1-3mm of surrounding skin shows freezing, and each cycle should last 15 seconds. Next, the lesion will be left to thaw completely before starting the second cycle. This process will be repeated every 2 weeks for 5 sessions, and can be discontinued if complete resolution is achieved early
