Skin wart is an infectious disease of human papillomavirus(HPV). Its clinical and histopathologic characteristics are largely determined by lesion sties, viral type and host immunity. The infected basal cells and keratinocytes of the epidermis are induced to proliferate by the viral genome. It is, however, not well known how htose factors give rise to histopathologic alterations in the infected basal cells and keratinocytes. So, evaluation of correlation between HPV antigen expression in the wart tissues and clinical and histopathologic charateristics was done on 83 cases of skin warts. The age of patients ranged from 2 to 83 years. Thirty six(43.3%) cases were diagnosed before the age of third decade. The sex ratio was nearly same. Verruca vulgaris was most common(46 cases), followed by verruca plana(26 cases) and verruca palmoplantaris(11 cases). HPV antigen expression was observed in 43 out of total 83(51.8%). It was noted in 47.8%(22/46) of verruca vulgaris, in 46.2%(12/26) of verruca plana and in 81.8%(9/11) of verruca palmoplantaris. HPV antigen-positive groups included more younger patient's age and more higher PCNA than those of HPV negative groups. HPV positive groups also tend to have shorter duration of disease and more numerous mitoses than HPV negative groups. HPV antigen-positive groups showed lower inflammation grade than that of HPV negative groups(p<0.05). The higher the inflammaton grade is, the lower the HPV antigen expression rate. In summary, HPV antigen expression in cutaneous wart tissue is significantly correlated with the proliferative activity of the lesion. It is also significantly correlated with the inflammation that is considered to be the result of cell-mediated immune reaction.
