We have previously cloned human papillomavirus type 82 (HPV-82) from a vaginal intraepithelial neoplasia, but it is not known whether HPV-82 can induce a cutaneous lesion. A large erosive nodule developed on the scrotum of a 50-year-old Japanese patient. Histopathologically, the lesion was composed of two distinct parts; one part showing changes characteristic of Bowen's disease in the epidermis, and the other showing elongated rete ridges and proliferation of atypical basaloid cells in the dermis. These parts were partially connected, giving the diagnosis of Bowen's carcinoma. Immunohistochemically, HPV capsid antigen was detected only in the nuclei of a few cells on the upper part of the epidermis. HPV-82 was identified in the lesion by blot hybridization and viral DNA was demonstrated in the lesion by in situ hybridization. HPV-82 has tropism for both the skin and the genital regions.
