Warty squamous cell carcinoma (WSCC), a rare variant of squamous cell carcinoma occurring in younger women, is primarily associated with human papillomavirus (HPV) infection. Although WSCC appears to exhibit less aggressive behavior than typical well-differentiated squamous cell carcinoma, it bears the risk of regional metastasis. Accordingly, WSCC should be differentiated from other verruciform neoplasms. We describe a rare case of WSCC with a short disease duration occurring in a woman of old age. We found the presence of HPV DNA different from other well-known types of high risk and low risk HPV by DNA chip microarray. These results suggest that various types of HPV can be associated with the pathogenesis of WSCC.
