Abstract

Background: The association between human papillomavirus (HPV) and squamous cell carcinoma (SCC) has been reported; however, the prevalence of HPV infection varies, and the clinical characteristics of HPV-positive cases remain unknown.

Objectives: To elucidate the frequency of HPV infection in a series of Japanese patients with SCC and to identify the characteristics of HPV-positive cases.

Methods: We evaluated 38 patients with SCC treated at our department. HPV typing was performed using SCC samples from different body sites. Immunohistochemical staining for HPV proteins and p16(INK) (4a) was performed, in addition to polymerase chain reaction and in situ hybridization. The clinical characteristics of the HPV-positive cases were clarified.

Results: Two genital lesions were positive for HPV type 16. Both cases showed basaloid features histopathologically, and were considered to have SCC that had arisen from bowenoid papulosis. p16(INK) (4a) expression was observed in 11 cases, including the two HPV-positive cases.

Conclusions: The present study indicates that the prevalence of HPV is not high and that bowenoid papulosis is an HPV-associated precancerous lesion. Further investigation is necessary to assess the relationship between HPV infection and SCC.
