| Abstract | ||
| Background Warts, caused by HPV, exhibit hyperkeratosis, papillomatosis, and Koilocytes histopathologically. Nd: YAG laser provides photothermal destruction, while PPD offers an immunotherapeutic approach for treating palmoplantar warts. Purpose: To compare the histopathological effects of Nd: YAG laser monotherapy versus Tuberculin PPD in treating palmoplantar warts. Methods: Sixteen patients were divided into two groups: one received Nd: YAG laser sessions every 4 weeks (4 sessions), while the other received intralesional PPD every 2 weeks (6 sessions). Biopsies were taken before and after treatment (4 months). Histopathological analysis was performed using H&E and p16 immunohistochemistry. Results: In the Nd: YAG group, koilocyte count significantly decreased from 142.67±55.4 to 24.5±42.1 (p < 0.028), whereas PPD treatment showed a nonsignificant reduction (143.5±50.2 to 130.3±80.0, p = 0.753). Rete ridge elongation significantly reduced in the Nd: YAG group (17.83±6.6 to 8.17±8.8, p < 0.027) but not in the PPD group (p = 0.115). p16 expression also significantly decreased with Nd: YAG (54.39±4.6 to 13.9±16.4, p = 0.028), while PPD had a nonsignificant effect. Conclusion: Nd: YAG laser was more effective than PPD in reducing koilocytes, rete ridges, and p16 expression. | ||
