Two Cases of Doughnut-shaped Warts Following Cryosurgery / 대한피부과학회지

ABSTRACT

Warts are benign proliferations caused by human papillomavirus (HPV) that commonly involve the skin and other epithelial tissues. Many therapeutic modalities are available for the treatment of warts. We report 2 cases of doughnut-shaped warts following cryosurgery with liquid nitrogen. Our cases demonstrate that, after removal, relapse of warts within a few weeks is frequent and probably due to sub-clinical or latent HPV infections surrounding the warts. Our cases suggest that we should be aware of possible recurrence and that adjuvant therapy, such as immune response modifiers with potent antiviral activities, should be used to reduce the incidence of wart recurrence after cryosurgery.
