Sažetak Leukoplakia is potentially a premalignant lesion and, in a small number o f cases, invasive carcinoma occurs at the same site. In recent literature, the commonly accepted rate of malignant transformation varies between 3 and 6%. Among the methods advocated for the treatment of these lesions are cryosurgery, chemical peel, surgical excision, and C 02 laser vaporization. In the following case, bilateral lesions in buccal mucosa with a 5-year history of development are presented. Utilizing local anesthesia, the involved surface epithelium and submucosa on each side were treated at 7-day interval with a continuous wave C 02 laser vaporization, 2.0 mm defocused spot at 10.0 watts. Mucosal destruction was carried out to the depth at which muscle fibers could be seen with arbitrary margins of approximately 5 mm. Lesions were followed up after 1, 3, 6, 9, and 12 months following surgery and there was neither recurrence nor any other intercurrent problems observed.
