Epidermodysplasia verruciformis-3 (EV3) is characterized by onset in childhood or early adulthood of persistent disseminated flat warts and pityriasis versicolor-like lesions of the skin that are induced by cutaneous human papillomaviruses (HPVs) of the beta genus. Some patients develop nonmelanoma skin cancer, particularly on areas of the body exposed to the sun. Patients are otherwise healthy and normally resistant to other microorganisms, including other viruses and skintropic pathogens, and even all other cutaneous and mucosal HPVs (de Jong et al., 2018).
