There is a considerable need for effective and safe treatment of cutaneous herpesvirus lesions. Current common approaches are limited to expensive or multidose oral pills. This systematic review of evidence-based approaches to phototherapy for the various manifestations of the herpesvirus discusses original publications of controlled clinical trials and case reports that were identified through searches in PubMed, MEDLINE, and Ovid. Interventions included photodynamic therapy (PDT), UV light, and near-infrared lasers. Nearly all studies (10 of 11) saw reduction of most or all lesions and extended time before reactivation of the virus. Side effects often were minimal to nonexistent, usually mild erythema at sites of phototreatment. Serious side effects included first-degree burns and linear IgA dermatosis, which were not common. Evidence from the reviewed literature indicates that short-term efficacy from treatment with phototherapy is the most likely outcome. However, long-term effects and follow-up of this treatment modality are lacking but appear promising. We recommend future studies to include more patients, determine the most effective type of phototherapy, and assess long-term follow-up. Furthermore, light-based therapies can be considered a reasonable alternative in situations that preclude traditional drug-based therapies.
