Successful Treatment with Topical Diphenylcyclopropenone for Three Cases of Anogenital Warts in Children

Anogenital warts are caused by human papillomavirus types 6 and 11. They are rare in children, and treatment is difficult since conventional treatments are generally painful and require the patient to be anesthetized. Topical diphenylcyclopropenone (DPCP) is a contact immunotherapy used for treatments of recalcitrant warts and alopecia areata. We herein report 3 cases of anogenital warts in children successfully treated with topical DPCP. Our results suggest that topical DPCP may be a valuable option for the treatment of anogenital warts in children who have difficulty with painful destructive therapy
