Cutaneous viral infections result from the complex interaction between viruses and skin structures, influenced by viral tropism and the host immune response. They can generate lesions ranging from transient rashes to chronic or potentially tumorous formations. Cutaneous manifestations are often the first sign of infection and allow for early recognition. The aim of this review is to analyze the role of viruses in skin pathology, the mechanisms of infection, and the clinical impact. A narrative review of the recent literature was performed, including original articles, systematic reviews, and clinical guidelines on cutaneous viral infections. Data on pathogenic mechanisms, types of lesions, evolution, and therapeutic options were evaluated, covering the main viruses involved in dermatology: herpesviruses, papillomaviruses, poxviruses, and viruses associated with acute rashes. Cutaneous viral infections can be self-limited, recurrent, or chronic, and some can promote malignant transformation of skin cells. The variability of clinical manifestations reflects the virus–host interaction and influences diagnosis and management. Recent advances highlight the development of vaccines and targeted antiviral therapies, which improve prognosis and infection control. Viruses play a major role in the etiology of skin diseases, and their early recognition is essential for preventing complications. Understanding the mechanisms of infection and the cutaneous response contributes to the optimization of therapeutic and preventive strategies, strengthening the modern management of viral cutaneous pathology.
