Abstract
Although periungual warts usually regress spontaneously in two or three years, they are unsightly and cause discomfort and physical impairment. Surgical removal of warts leaves a scar. Among therapeutic means of removal are liquid nitrogen, cantharidin, monochloroacetic or trichloroacetic acid, “maceration” with salicylic acid ointment, and irradiation. The preferred agent is liquid nitrogen.
