Porokeratosis plantaris discreta is a distinct clinical and pathological entity often resistant to conservative management. Twenty-one lesions of porokeratosis plantaris discreta were treated cryosurgically in 11 patients. Removal of the blister roof two weeks after cryosurgery with retreatment of any residual lesion proved an effective method for removal of such lesions without scarring. A cure rate of 90.5% was achieved using this technique.
