Human immunodeficiency virus (HIV) causes disease by infecting lymphocytes and progressively destroying critical regulatory and effector cells of the immune system, leaving patients vulnerable to a number of bacterial, fungal, and viral infections. Facial herpes (herpes simplex virus-1 [HSV-1]), genital herpes (HSV-2), herpes zoster (varicella zoster virus), oral hairy leukoplakia (Epstein-Barr virus), Kaposi’s sarcoma (HHV-8), molluscum contagiosum, condyloma acuminata (human papillomavirus [HPV-6, HPV-11]), plantar warts (HPV-1), and facial warts and flat warts (HPV-5) are some of the cutaneous viral diseases most commonly seen in HIV-infected patients. Two immunomodulatory agents, imiquimod (Aldara), shown to be safe and effective in the management of genital warts, and alitretinoin gel, shown to be safe and effective in the treatment of Kaposi’s sarcoma, may offer a new therapeutic approach to treatment of cutaneous viral diseases. There is a strong scientific rationale to suggest that imiquimod and alitretinoin gel may be useful in the treatment of a variety of cutaneous viral diseases that have been shown to respond to immunomodulatory drugs. This represents a new approach in the therapeutic treatment paradigm for treatment of cutaneous viral diseases at their site of infection.
