Intralesional cidofovir in the treatment of cutaneous warts in a renal transplant patient.

Background: Cutaneous warts are often recalcitrant to conventional therapy in immunocompromised patients. Cidofovir is a potent antiviral agent shown to have a broad spectrum of action against DNA virus, including human papillomavirus.
Objective: To determine the efficacy of intralesional cidofovir in the treatment of florid warts in an immunocompromised renal transplant patient.
Method: The patient received seven injections of intralesional cidofovir at 4 week intervals in his numerous palmar warts.
Conclusion: Based on our results, intralesional cidofovir is a promising therapeutic modality in the treatment of cutaneous warts in the renal transplant population.
