Human papillomavirus infection is one of the most common and most distressing cutaneous diseases in patients with HIV infection. It is also a common, and often therapeutically challenging, infection in individuals who are immunologically competent. A wide range of therapeutic options exists for treating cutaneous human papillomavirus infections, but none is uniformly effective. In this report we describe a man with HIV-1 infection and disfiguring facial verruca vulgaris who demonstrated complete clinical response to intravenous cidofovir. Our report provides further support for the use of intravenous cidofovir as therapy for treatment-resistant and/or widespread cutaneous human papillomavirus infection.
