To evaluate the efficacy of bleomycin and cryopreservation in the treatment of plantar verruca by dermoscopy and explore the influencing factors. Compare the safety, economic burden and impact on quality of life of the two treatments

Our research aims to evaluate and compare the effectiveness of bleomycin and cryotherapy in treating plantar warts. First, we enrolled patients according to eligibility criteria. Second, the patients were assigned to two groups randomly. One is Bleomycin Group and the other is Cryotherapy Group which means two -group-patients were received different therapies. Thirdly, we compared the efficiency of two groups by using dermoscopy. Finnally, we used statistical analysis to analyze the research data and draw the experimental conclusions.
