Comparative evaluation of carbon dioxide laser and cryotherapy by dermoscopy in treatment of warts

Background Viral warts are common pores and skin manifestations visible in each youngster and adults owing to the human papillomavirus. Human papillomavirus is transmitted at once with the aid of touch or in a roundabout way via the surroundings. AIM and Objective The aim of our study was to compare the results of two therapeutic modalities, carbon dioxide (CO2) laser and cryotherapy, in the treatment of warts collectively with the dermoscopic assessment of viral warts before and after applying treatment. Methods A total of 50 patients were clinically recognized as having common warts and were recruited from the Dermatology Outpatient Clinics of Assiut University and Luxor preferred Hospitals. All patients were subjected to history taking and scientific and dermoscopic evaluations. In our study, we examined the efficacy of treatment of common warts using cryotherapy and CO2 laser according to improvement in size and width of warts, using dermoscopy, which helped us in our observation to attain a medical diagnosis of warts easily and correctly. Results and Conclusion CO2 laser can be an effective and time-saving modality for warts and is a better modality than cryotherapy. However, studies with larger sample sizes and longer follow-up durations are suggested, which will verify the veracity of these results.
