Abstract:
Two new papillomaviruses, HPV 40 and HPV 57, were isolated from a PIN lesion and an inverted papilloma of the maxillary sinus, respectively. HPV 40 showed a 13% homology to HPV 7 by reassociation kinetics and HPV 57 showed a 17% homology to HPV 2 and 25% homology to HPV 27. Hybridization of the DNA of these papillomaviruses to a wide variety of different tumor biopsies revealed that HPV 40 was present in a few genital condylomata acuminata as well as in bowenoid lesions. HPV 57 DNA was present in an oral wart, a genital condyloma acuminatum, and verrucae vulgares lesions from two immunosuppressed patients.
