    Re-evaluation of epidermodysplasia verruciformis: Reconciling more than 90 years of debate.
    J Am Acad Dermatol 2017 Feb 10. Epub 2017 Feb 10.
    Department of Dermatology, Hadassah-Hebrew University Medical Center, Jerusalem. Electronic address:
    Epidermodysplasia verruciformis (EV) is a rare genodermatosis characterized by abnormal susceptibility to cutaneous human beta-papillomavirus infections causing persistent flat warts or pityriasis versicolor-like lesions. This generalized verrucous skin disorder resembles generalized verrucosis, but these 2 conditions are distinguished by differences in clinical manifestation and the human papillomavirus types involved. A breakthrough in our understanding of EV was the discovery that homozygous inactivating mutations in TMC6 (EVER1) and TMC8 (EVER2) determine susceptibility to this disorder; however, they have not solved all EV cases fully.
