In addition they are usually located in cosmetically important areas, so therapy should be as mild as possible, and potential scarring should be avoided. Ultraviolet a radiation refers to electromagnetic radiation with wavelength (320-400nm) which penetrate deeper into dermal structures' and carry less energy when compare to UVB. Objective:To evaluate the efficacy and safety of ultraviolet A in the treatment of plane warts. Patients and Methods:Open therapeutic study was conducted indepartment of Dermatology, In Baquba Teaching Hospital,Diyala health directorate.A total of 60 patients with plane warts aged from 4 to 29 yearswere enrolled in the study between June 2015 to May 2016,all treated with ultraviolet A light,the treatment continue for 3 sessions/week (every other day) for 4 weeks. Results: Six patients were healed two weeks from starting of treatment, 35 patients were healed after completion of treatment(4 weeks),four patients healed four weeks after stopping of treatment,15 patient showed no response to UVA in treatment of plane warts.no significant side effects observed other than transient erythema and postinflammatorypigmentary changes.
