This study reports a case of oral leukoplakia (OL) treated using a high-power diode laser. A 61-year-old male smoker and drinker, presented an asymptomatic tongue lesion. A white plaque located on the lateral border of the tongue on the left side was observed during intraoral examination. The lesion measured 4 cm in its largest diameter and presented well-defined contours and irregular borders. After clinical diagnosis of OL, an incisional biopsy was performed. The histopathologic exam showed mild dysplasia, and complete removal of the lesion was done with a high-power diode laser (808 nm, 2.5 W, continuous mode) in 2 surgical procedures. The first area removed presented mild dysplasia and the second presented moderate dysplasia. After 3 months, there was recurrence of the lesion, also treated with a surgical laser, and the microscopic findings revealed severe dysplasia. The patient remains in follow-up for 1 year, with no evidence of recurrence or malignant transformation.
