title: Development of squamous cell carcinoma by two high-risk human papillomaviruses (HPVs), a novel HPV-67 and HPV-31 from bowenoid papulosis.
abstract: We report a patient with bowenoid papulosis (BP) involving two high-risk human papillomaviruses (HPVs) and the development of invasive squamous cell carcinoma (SCC). Our patient showed verrucous lesions on the penis, perianal area and groin that had been noted over the previous 8 years and had recurred after all therapeutic approaches. The perianal and left inguinal lesions revealed invasive SCC on histology. HPV-31 and HPV-67 sequences were detected by polymerase chain reaction from BP lesions of the perianal area and the shaft of the penis. HPV-31 has already been reported in BP as a high-risk HPV for the development of SCC, but HPV-67 is a novel one that has never been reported in BP. As HPV-67 has sequence homology to HPV-52 and HPV-58, it belongs to the family of HPV-16, a high-risk HPV group. Thus our patient showed two high-risk HPVs, i.e. HPV-31 and the novel HPV-67, which may be directly involved in the development of SCC.
