Psoriasis is a chronic inflammatory disease affecting the skin with various treatment options. Cryosurgery has been studied in only a limited number of case series for the treatment of small plaque psoriasis with variable results. Findings from these studies suggest cryosurgery can improve the induration, erythema, and scaling of small psoriatic plaques with one or just a few treatments. Furthermore, these studies suggest that cryosurgery is a safe treatment modality with hypopigmentation as the only major adverse effect. However, further studies are necessary to clarify the role of cryosurgery in the armamentarium of psoriasis therapy.
